Two-hadron single target-spin asymmetries: first measurement by HERMES

High Energy Physics - Experiment 2019-08-14 v1

Abstract

Single target-spin asymmetries in semi-inclusive two-pion production were measured for the first time by the HERMES experiment, using a longitudinally polarized deuterium target. These asymmetries relate to the unknown transversity distribution function h1(x)h_1(x) through, also unknown, interference fragmentation functions. The presented results are compared with a model for the dependence of one of these interference fragmentation functions on the invariant mass of the pion pair.
