Description
We present predictions for antiproton production cross sections in proton–proton collisions, which describe the interaction of cosmic rays with the interstellar medium. The aim of the project is to test a claimed excess in the production of secondary vs primary antiprotons in pp collisions against the QCD factorization framework. We quantify the uncertainties of the involved cross sections in terms of PDFs, FFs, and missing higher orders and highlight the importance of understanding the low transverse momentum region for these specific observables.
