Conventions for text:
 
It is suggested to follow this guidelines for editing a text. The PPR had been prepared using these guidelines.
It is very helpful to have a common use within the Collaboration.
 
Basic rules in short: 
in italics ($..$) symbols
in roman, NOT in italics: units, particle names, abbreviations, chemical symbols, the integrand 'd'
 
examples:
A proton p has a momentum $p$.
An electron e has an electric charge $e$.
 
Some examples often used.
 
$\sqrt(s_{\mathrm NN} = 2.76$ TeV 
 
transverse momentum: $p_{\mathrm T}$    index not in italics
 
d$N$/d$y$
 
pp collisons and Pb--Pb (long dash Tex--) collisions is mostly used.
 
in Tex one can use:
 
\newcommand{\pip}{$\pi^{+}$}
\newcommand{\pim}{$\pi^{-}$}
\newcommand{\kap}{K$^{+}$}
\newcommand{\kam}{K$^{-}$}
\newcommand{\pbar}{$\rm\overline{p}$}
\newcommand{\degree}{$^{\rm o}$}
\newcommand{\s}{$\sqrt{s}$}
\newcommand{\pt}{\ensuremath{p_{\rm t}}}
\newcommand{\dedx}{d$E$/d$x$}
\newcommand{\dndy}{d$N$/d$y$}
\newcommand{\dndydpt}{${\rm d}^2N/({\rm d}y {\rm d}p_{\rm t})$}
\newcommand{\pp}{pp}
 
Hyphenation: Please note hyphens may have been inserted in word pairs that function as adjectives when they occur before a
noun, as in “x-ray diffraction,” “4-mm-long gas cell,” and “R-matrix theory.” However, hyphens are deleted from word pairs
when they are not used as adjectives before nouns, as in “emission by x rays,” “was 4 mm in length,” and “the R matrix is
tested.”


It is also suggested to use the xx.bib option in tex.
You can get the references in this format from SPIRES avoiding typing errors
BibTex makes for you the sorting of the references
