Preparing contributions to CERN reports (school, workshop, and conference proceedings)

AbstractThis document explains instructions for authoring CERN Reports which are processed by the CERN E-Publishing Service.


Authors must observe the following instructions to ensure consistency and uniformity in the style and layout of CERN Reports. Wherever possible, each contribution will go directly to be printed, without any editing, and should therefore be in its final form.

Although the typesetting rules that are described are of a general nature, the present document emphasizes their use with LaTeX.Templates and more detailed information for Word users are available on the E-Publishing Service Web site (Word Section at the page

Note that it is the author’s responsibility to obtain permission from the copyright holder if material taken from other sources is included in the source submitted as a CERN Report.

Generalities on typing

When submitting your electronic source in LaTeX, you must use the cernrep class file, which is available from the E-Publishing Service Web site ( Moreover, specific instructions for preparing your LaTeX contribution are given in the appendices.

Format for the text

Take care that your material stays inside the text frame which is 16 cm \(\times\) 24 cm (i.e., a A4 sized paper has 3.0 cm margins at the top and at the bottom, and 2.5 cm left and right). This is expecially true for figures and tabular content.

Your contribution should be preceded by an abstract of not more than 150 words, written as a single paragraph. The abstract should not include notes or references and should provide a brief summary of the work.


Please provide up to a maximum of 6 keywords. These will be used for indexing purposes. You should avoid the use of general and plural terms and use of multiple concepts (avoid using "of" and "and"). Do not use abbreviations unless they are established and easily recognizable in the field.

Sectioning commands and paragraphs


The standard LaTeX commands \section (level 1), \subsection (level 2), \subsubsection (level 3), \subsubsubsection (level 4), should be used for headings. Do not start a new section on a new page, but continue on the same page.

In the text, leave a blank line after each paragraph.



Equations should be treated as part of the text, and therefore p
