Letters: must describe new and original work deserving rapid publication. Their aim is fast and concise communication of material of current interest:
- an important theoretical, computational or experimental result
- a valuable discussion of, or a short essay on, an open scientific issue
- a valuable presentation of innovative and promising ideas and concepts
in the fields covered by the journal. In order to make a fast refereeing and decision procedure possible, and to address a broad readership, Letters should not exceed 4 printed pages in the EPJ style format, and should contain no more than 4 figures and/or tables.

Regular Articles: 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.

Tools for Experiment and Theory/Scientific Notes: are articles presenting original and new developments of particle detectors, readout electronics, computational methods or analysis tools. Direct relevance to physics topics within the "Aims and Scopes" must be demonstrated.
An important subgroup are Scientific Notes, typically based on internal notes of experimental collaborations, detailing specific aspects of importance for understanding and assessing the physics results presented in large collaboration papers.
Technical details down to the level of construction drawings, electronic circuit diagrams or computer codes should not be included but may be added as electronic-only supplementory material.

Reviews: 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.
