Letters must describe new and original work deserving rapid publication. Their aim is to concisely report on important theoretical, computational or experimental results or on sufficiently substantiated concepts, with a significant (potential) impact on the broader development in one of the fields covered by the journal. In order to allow a rapid refereeing and decision procedure and to better address a broad readership, Letters should not exceed 4 printed pages in EPJ A format, and should include no more than 4 figures and/or tables.
Letters to the Editor:
Are by invitation only and serve the purpose of initiating targeted, high-level discussions on open scientific issues, or on more speculative but truly innovative and promising ideas for the future development of the field. Their format style is similar to that of regular Letters. While external proposals for new, and comments on previously published Letters to the Editor are possible, the decision to act on them rests solely with the editors in charge of this section.
Describe original work, or provide details of original work previously published in a Letter article. There is no general limitation of the overall size nor of the number of figures, nor of the level of details considered to be necessary.
New Tools and Techniques:
Are articles presenting original and new developments in particle detectors, readout electronics, computational methods, theoretical frameworks or analysis tools. An important subgroup consists of articles detailing specific aspects of importance to understanding and assessing either the formalism outlined in a theoretical or computational paper, or the analytical tools that lead to the physics results presented in experimental collaboration papers. A direct relevance to physics topics within the “Aims and Scopes” must be demonstrated. Technical details (including but not limited to construction drawings, electronic circuit diagrams or computer codes) may be added as electronic-only supplementary material.
Are by invitation only through the Editorial Board. There is no general limit to the overall length -- they may contain, but should not be restricted to, original work. Reviews will fall into one of the following categories:
1) Comprehensive reviews of major topics within the "Aims and Scope" of EPJA and EPJC. Their primary assets will be pedagogical exposition, synthesis of key developments, and the inclusion of a definitive and representative bibliography.
2) Technical papers presenting an extensive review of a specialist topic within the "Aims and Scope".
3) Reviews of a newly emerging field, providing an up-to-date synthesis and an extended discussion of the open questions. The discussion is expected to lead to an assessment of the possible further developments within the field, potentially making a substantial contribution to guiding decisions concerning the planning or running of experimental and observational facilities.
4) Outstanding thesis or working reports, the richness and importance of whose details justify the exceptional publication of the full length work.
