Cosmic-ray (CR) physics in the GeV-TeV range has entered a precision era with recent data from space-based experiments. However, the poor knowledge of nuclear reactions (production of antimatter and secondary nuclei) limits the information that can be extracted from these data (such as source properties, transport in the Galaxy, indirect searches for dark matter).

The first edition of this workshop was held in 2017 (XSCRC17). Its goal,  bringing together different communities (CR theorists, CR experimentalists, nuclear and particle physicists), was to review theoretical motivations for CR studies, new CR data, and how the modelling of CRs crucially depends on nuclear reactions. The workshop was also strongly aimed at presenting current efforts and discussing forthcoming perspectives for particle/nuclear measurement campaigns.

This second edition, XSCRC2019, reviewed the advances made and highlighted some results obtained thanks to collaborations started during the first edition.

The 2024 edition, XSCRC2024, has further strengthened these emergent synergies, taking advantage of the complementarity and know-how in different communities: the challenges that pose the interpretation of high-precision CR data can only be undertaken with a collective and coordinated effort. The round tables were oriented to write a white paper, which is now published as a Physics Report  (https://www.sciencedirect.com/science/article/pii/S0370157325003096?via%3Dihub).
