  "account": "The Physics of the Cosmos Community Cross Sections Science Program is launching the Cross Sections for Cosmic Rays Science Analysis Group (XS SAG). This group aims to compile the status of current and upcoming cosmic-ray space-based and balloon-borne experiments, as well as the relationship between these measurements and ground-based nuclear cross-section measurements.\n\nThe XS SAG will have open membership, inviting participants from the PhysPAG, relevant Science Interest Groups, and the broader astrophysics and particle and nuclear communities. Their goal is to enhance understanding of the galaxy using cosmic rays, by addressing key questions in the GeV-to-TeV energy range.\n\nThese questions include the potential to reveal dark matter with cosmic rays, the synthesis and acceleration locations of Galactic cosmic rays, refinement and expansion of the cosmic ray transport model, and moving beyond the standard paradigm for sources. By compiling and analyzing cross sections data from various cosmic-ray experiments, the XS SAG hopes to make significant strides in answering these critical questions in cosmic-ray physics.",
