Transverse single-spin asymmetries in proton-proton collisions at the AFTER@LHC experiment

摘要

We present results for transverse single-spin asymmetries in proton-protoncollisions at kinematics relevant for AFTER, a proposed fixed-target experimentat the Large Hadron Collider. These include predictions for pion, jet, anddirect photon production from analytical formulas already available in theliterature. We also discuss specific measurements that will benefit from thehigher luminosity of AFTER, which could help resolve an almost 40-year puzzleof what causes transverse single-spin asymmetries in proton-proton collisions.
