Single-transverse-spin asymmetries: From deep inelastic scattering to hadronic collisions
Single-transverse-spin asymmetries: From deep inelastic scattering to hadronic collisions
We study single-spin asymmetries in semi-inclusive deep inelastic scattering with transversely polarized target. Based on the QCD factorization approach, we consider Sivers and Collins contributions to the asymmetries. We fit simple parameterizations for the Sivers and Collins functions to the recent HERMES data, and compare to results from COMPASS. Using …
