We invite all participants to contribute to the proceedings volume, which is a thematic issue at the International Journal of Modern Physics A

This thematic issue will feature papers on the latest developments in particle correlations and femtoscopy, a set of techniques used to study the space-time structure of particle-emitting sources and final-state interactions in nuclear and particle collisions. Topics covered include all subjects of the WPCF series. Submission deadline is 30 September 2026.

Submissions are expected to present original and unpublished work, including new results or analyses, updates to existing findings, or substantive discussions and interpretations thereof. Naturally, we also accept papers authored by representatives of collaborations ("X. Y. for the ABC Collaboration"), provided that the submitted papers report the latest results and avoid reproducing verbatim texts and content already published in another journal or conference proceedings. In other words, we expect collaboration papers to include new material, minor updates to results, or additional discussion of ongoing or future work.
