I am currently writing my dissertation (proposal) in Org-mode. So far
it is working very well for me, I can export to both PDF for more formal
submissions to my adviser and to HTML for less formal posting to a web
page. I keep *all* of my reading notes as Org-bibtex headlines in a
single large reading.org file. I have a (somewhat complex) system
whereby I am able to reference these bibtex entries from the
dissertation and automatically generate the required .bib file as part
of my document export process. One nice side effect of this setup has
been the ability to do a fun graphical export of my references [1].
My entire dissertation directory is in a public git repository [2], you
may find my Makefile [3] useful (although again I should warn you that
my particular setup may be needlessly complex).

I've not run into any such problems. I tend to construct all of my
labels through Org-mode (which works well for export to both HTML and
LaTeX).

I deal with the above by not placing spaces in such commands, so the

\cite{SomeAuthorReference,AnotherReference}

My setup is to keep a tasks.org file with reading related tasks which
holds Org-mode links to all of my references. As part of my document
export process I scan through that file, jumping to each link and
running `org-bibtex-export-to-kill-ring' at each reference. I then dump
all of these bibtex entries into a .bib file. By using a Makefile rule
the .bib file is only regenerated when I've changed my tasks.org file.

This always feels hacky, but I just place this command at the end of the
document in whatever section (usually "conclusion") that may be.

When preparing a JSS paper for publication [4] we found that to satisfy
some of the Journal's specific formatting rules we had to add a new
document class, add a new link type, and post-process the generated
LaTeX. The entirety of this customization may be found here [5] -- the
Makefile in that directory may also be helpful.
In summary, I have very much enjoyed writing longer documents in
Org-mode (on those few occasions when all authors are Org-mode users).
With the ability to write in-line latex it is possible to meet any
stringent output requirements.
I hope this helps,

Thanks for your helpful advice! Your org-bibtex setup in particular
looks like exactly what I need. (Your dissertation proposal looks very
interesting, too!)
I think what I will do is stick with Org for now, and try to be smarter
about a few things (like the #+LABEL command...which I must have read
about at some point but forgotten) so that, if I ever need to drop down
to straight LaTeX, it will be easy to make the switch. You've given me
a helpful example to follow.
Best,
Richard

Could you describe how to do section links and references from within
Org. I have tried to figure this out for a while now. The only
solution I can find (on Worg) depends on precise section names, which is
not so stable. I use the new latex export engine

Aloha Richard,
The current Org-mode LaTeX exporter is nifty, but it was designed to
export notes and not dissertations. It can be configured to do that,
but the extra translation step adds some complexity and potentially
introduces problems. In my work this potential downside is more than
made up for by the reproducible research facilities of Org-mode. When I
don't need these, I typically write in LaTeX. The AucTeX environment is
a terrific help to the author of a LaTeX document and in many ways it is
ideal for a dissertation writer.
That said, the new LaTeX exporter in Org-mode is being designed to
overcome some of the limitations of the old exporter, so it will
probably be the case that the translation step from Org-mode to LaTeX
will get easier. It would be good to have someone write a dissertation
using the new exporter because it might stretch the exporter in ways
that smaller, simpler documents do not. But I doubt if this will be the
path of least resistance to the finished dissertation.
I'm using ebib to manage BibTeX data now and I really like it. It works
well with both LaTeX and Org-mode, so I don't have to switch gears
completely to move from one authoring environment to the other.
hth,
Tom

Thanks for your advice. This has been my experience so far as well.

I have seen mention of the new exporter on this list a bit, but I don't
read the list enough to know where to find it. How can I try it, if I
want to see how it compares to the current exporter? Is it in a public
branch somewhere? Would feedback from me be helpful?

Hmm, I hadn't heard of ebib, but I will have a look at it. Thanks for
the tip!

Assuming contrib directory is in your load-path, just evaluate
(require 'org-export)
Then, you can call the dispatcher with M-x org-export-dispatch.

Certainly.

Or in ConTeXt...
Sorry, I can't answer your questions about Org-mode. I just know, that
ConTeXt is a much better tool for writing dissertations than LaTeX is.

Since others have added their bits, I'll just say I wrote my Master's
thesis in Physics last year with the then org-mode HEAD. I rather liked
the process and the end result[1]. Although I have to admit, I had to
hack around a bit because of buggy mandatory templates from my
university. Apart from that, everything was very smooth. If you are
interested, my org-mode setup is in a public repo[2]. However I haven't
had the time to make the org source for the thesis publicly available.
In case you are interested, I'm attaching some relevant bits. It has
examples on how to put in tables (with short and long captions),
figures, latex snippets and finally how I included a bibliography and
appendices.
Hope this will help.

* Introduction
** The Standard Model :SM:
\label{chap:SMintro}
The Standard Model is a quantum field theoretical approach to
describe interactions in nature. The theory is primarily built upon
symmetry arguments supported by experimental data. It describes the
interactions between all fermions mediated by vector gauge bosons.
These include the electromagnetic, weak and strong interactions.
The formulation of the SM does not include gravity. There are
various approaches to include gravity in BSM theories which are
discussed elsewhere \cite{ArkaniHamed:1998rs,Randall:1999ee}.
#+CAPTION: [Interactions and particles described by the SM.]{The interactions and the participating particles described by the Standard Model are tabulated below. Although the $Z^0$ is listed both as force carrier and a particle interacting by the weak force, it should be noted it does not couple with another $Z^0$.}
#+LABEL: tbl:interactions
|----------+-----------------+----------------+---------------------------------|
| Charge | Force | Force carrier | Interacting particles |
|----------+-----------------+----------------+---------------------------------|
| Electric | Electromagnetic | \gamma | all charged fermions, \(W^\pm\) |
| Weak | Weak | \(W^\pm, Z^0\) | all fermions, \(W^\pm, Z^0\) |
| Colour | Strong | \(g\) | all quarks, anti-quarks, \(g\) |
|----------+-----------------+----------------+---------------------------------|
In the SM all particles carry various charges which describe all
the interactions they undergo: the electric charge is responsible
for all electromagnetic interactions, the weak charge for all weak
interactions and the colour charge for all strong interactions.
Since any quantum fields have bosonic exchange particles, all the
interactions discussed earlier are associated with different spin-1
bosons as force carriers. This has been summarised in
\Tabref{tbl:interactions}.
*** Production and Decay of the \(W'\) Boson :pdf:

\noindent *Production:* The $W'$ boson is assumed to have a
coupling constant that is the same as its lighter SM counterpart.
This is known as the sequential SM $W'$ boson. The diagrams[fn:1]
responsible for the production of $W'$ bosons at a hadron
collider are known as charged current (CC) processes. These are
flavour changing interactions occurring between up-like and
down-like quarks (or anti-quarks) where the weak current involved
is charged as the gauge bosons involved are charged.
\Figref{fig:LO-Wprime} shows a diagram responsible for $W'$
production at the LHC.
The production of a heavy $W'$ boson from a pp collision depends
strongly on the momenta of the initial state particles. Since
protons are composite particles made of (anti-)quarks and gluons,
knowledge about the momentum fraction carried by the initial
state particles is important. This is achieved by a /Parton
Distribution Function/ (PDF) determined from deep inelastic
scattering experiments with hadrons and leptons. In 1968--69,
Bjorken proposed a dimensionless quantity /x/ which is
independent of the momentum transfer during a hard scattering
event. They exhibit a scaling behaviour in the asymptotic limit
of very high energy collisions, known as /Bjorken scaling/. The
discovery of scaling behaviour as predicted by Bjorken led to the
modern formulation of the strong force as an asymptotically free
quantum field theory \cite{Tung:2009}. The scaling was later
shown to be only approximately true at low energies due to higher
order QCD corrections (scaling violations).
In 1969 Feynman proposed the /parton model/. It describes hadrons
as composite particles made of its constituent quarks,
anti-quarks and gluons \cite{PhysRevLett.23.1415}. The
constituent quarks can be either valence or sea quarks. If the
quark is one of the three quarks forming the hadron bound state
and responsible for the quantum number, then it is called the
/valence quark/. On the other hand if it is a virtual quark
formed by splitting of gluons, it is called a /sea quark/.
Modern QCD explains the interaction of hadrons in hard scattering
experiments using this parton model.

\begin{equation}
\label{eq:partondistribfn}
\frac{d\sigma}{dm_T} = \sum\limits_{a,b} \int dx_A f_{a/A}(x_A,\mu) \int dx_B f_{b/B}(x_B,\mu) \frac{d\hat{\sigma}}{dm_T}
\end{equation}
#+end_src
The differential production cross section ($d\sigma/dm_T$) for
observing certain events in a channel in a hadron collider is
given by \Eqref{eq:partondistribfn}. $f_{a/A}$ and $f_{b/B}$ are
the parton distribution functions mentioned earlier. They are the
probability distributions of finding a parton of type /a/ (/b/)
originating from a hadron of type /A/ (/B/) with the momentum
fraction $x_A$ ($x_B$). $d\hat{\sigma}/dm_T$ is the parton level
cross section given by perturbative QCD. The Bjorken scaling
violations observed earlier could be incorporated into this
picture by including corrections to the PDFs from perturbative
QCD. These corrections introduce the dependence on the parameter
\mu in the PDFs. The parameter \mu is related to the
renormalisation of the strong coupling in the cross section
calculation and the QCD corrections to the PDFs. They are often
referred to separately as /renormalisation scale/ and
/factorisation scale/ \cite{Soper:1996sn}.

** Particle track parametrisation in ATLAS :trk:
\label{app:trackparam}
A particle track in ATLAS is represented by the perigee[fn:2] of the
track. The perigee is specified by the five parameters:
+ d_0 - transverse impact parameter, the distance of the closest
approach of helix to beam pipe,
+ z_0 - longitudinal impact parameter, the z value at the point of
closest approach,
+ \phi_0 - azimuth angle of the momentum at point of closest
approach, measured in the range $[-\pi,\pi)$,
+ \theta - polar angle in the range $[0,\pi]$,
+ q/p - charge over momentum magnitude.
In ATLAS the /z/-axis is parallel to the magnetic field (which is
parallel to the beam axis). \Figref{fig:trkperigee} shows the five
parameters split into transverse and longitudinal planes.

[[file:figs/Perigee.png]]
** Limit formalism :limits:
\label{app:limits}
The limits are set with the observed events in a bin with $m_T$ >
$m_{Tmin}$, where the lower bin threshold is determined by taking
the half of the $W'$ mass. The expected number of events are given
by \Eqref{eq:expevts}, where $\nbg$ is the expected number of
events from our background model and $N_{sig}$ is the predicted
number of signal events from \Eqref{eq:sigevts}. $L_{int}$ is the
integrated luminosity of the recorded data and $\epsilon_{sig}$ is
the event selection efficiency.
#+begin_src latex
\begin{align}
\label{eq:expevts}
N_{exp} &= N_{sig} + \nbg \\
\label{eq:sigevts}
N_{sig} &= L_{int} \epsilon_{sig} \SB
\end{align}
#+end_src
The likelihood function in \Eqref{eq:likelihood} is obtained from
Poisson statistics for $N_{obs}$ observed events. Uncertainties are
included as nuisance parameters in the analysis. They are assumed
to follow a Gaussian probability distribution. In this analysis we
consider uncertainties on $L_{int}$, $\epsilon_{sig}$ and $\nbg$ in
our calculations. Taking the above into consideration we get the
likelihood function shown in \Eqref{eq:llnuissance}.
#+begin_src latex
\begin{align}
\label{eq:likelihood}
\mathcal{L}(\SB) &= \frac{(L_{int}\SB + \nbg)^{N_{obs}}e^{-(L_{int}\epsilon_{sig}\SB+\nbg)}}{N_{obs}!} \\
\label{eq:llnuissance}
\mathcal{L}(\SB,\theta_1,\dotsc\theta_N) &= \frac{(L_{int}\SB + \nbg)^{N_{obs}}e^{-(L_{int}\epsilon_{sig}\SB+\nbg)}}{N_{obs}!} \prod g_i(\theta_i) \\
g_i(\theta_i) &= \frac{1}{\sqrt{2\pi}\sigma_i}e^{-\frac{(\theta -\bar{\theta}_i)^2}{2\sigma_i^2}} \nonumber
\end{align}
#+end_src
This likelihood function is used to calculate the log-likelihood
ratio (LLR) test statistic shown in \Eqref{eq:LLR}
\cite{Junk:1999kv}. The LLR is used to calculate /p/-values which
correspond to confidence levels for the signal + background
(CL_{s+b}) and background (CL_b) only hypotheses. These are
evaluated by conducting pseudo-experiments and integrating over the
corresponding LLR distributions.
#+begin_src latex
\begin{equation}
\label{eq:LLR}
LLR = -2 \ln \frac{\mathcal{L}(data\lvert s+b)}{\mathcal{L}(data\lvert b)}
\end{equation}
#+end_src
The CL_s method finally uses the ratio of the /p/-values to
determine the exclusion limits (\eqref[name=eq.~]{eq:CLs}). To set
the limits at 95% confidence level, the signal cross section is
increased until CL_s = 1 - \alpha where \alpha is 0.95. For a more
complete discussion of the limit setting procedure see the
referenced ATLAS internal note \cite{Adams:1317922}.

CL_s = \frac{CL_{s+b}}{CL_b}

Thanks! This is definitely helpful. The ignoreheading tag is a nice
hack -- fixes one of those niggling issues I've had with LaTeX export.

I would recommend LaTeX. In my experience, writing long documents (or
Beamer slides) in org-mode creates additional work, insofar as I have to
think through two layers of translation: 1) how to get org-mode to
translate nicely into LaTeX; and 2) how to get LaTeX to output the final
document I desire. In larger documents, "leaky abstractions" can quickly
become a problem. I tried writing in org-mode but ended up with a
document encrusted with all sorts of hacks (#+LaTeX: lines and the
like). IMO, writing in LaTeX/AUCTeX affords greater control over the
final document. (Note: the new export engine will give the user greater
ability to reduce the number of "leaks".)
I would recommend using org-mode if the following apply:
1. You will rely heavily on org-babel.
2. You anticipate having to output to multiple formats (e.g., your
dissertation advisor requires you to submit .doc files).
3. Your document structure will be straightforward.
I would recommend using LaTeX if the following apply:
1. You have numerous footnotes. (Fontification and export of footnotes
in org-mode can be painfully slow when a document contains hundreds
of footnotes.)
2. You are using biblatex. (If you are relying heavily on biblatex for
citations, then you will need to export to LaTeX to output your final
document, thus precluding the possibility of outputting to other
formats. Furthermore, AUCTeX offers very helpful syntax highlighting
and folding of citations and footnotes, along with excellent reftex
integration.)
3. You will be using a many cross-references.
My workflow is as follows. I rely on my org-mode files for drafting
small segments of a project. I then export the segments to the kill ring
with the following function and yank them into the relevant LaTeX file.
--8<---------------cut here---------------start------------->8---
(defun my-org-export-latex-to-kill-ring ()
(interactive)
(kill-new (org-export-region-as-latex (point) (mark) t 'string)))
--8<---------------cut here---------------end--------------->8---
Best,
Matt
