TLDR
In this paper, the Sivers distribution is extracted from the most recent experimental data of HERMES and COMPASS experiments, and a simple fitting strategy is used to explore the role of the proton sea quarks.Abstract:
Polarised Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes, l(Sl)p(S) → l h X allow to study Transverse Momentum Dependent partonic distributions (TMDs), which reveal a non trivial three dimensional internal structure of the hadrons in momentum space. One of the most representative of the TMDs is the so-called Sivers function that describes the distribution of unpolarized quarks inside a transversely polarized proton. We present a novel extraction of the Sivers distribution functions from the most recent experimental data of HERMES and COMPASS experiments. Using suitable parametrizations, within the TMD factorization scheme, and a simple fitting strategy, we also perform a preliminary exploration of the role of the proton sea quarks.read more

TL;DR: In this paper, single-spin asymmetries were investigated in electroproduction of charged pions and kaons from transversely polarized protons at the HERMES experiment, and they were studied as a function of the azimuthal angle about the beam direction between the target-spin direction and the hadron production plane, the transverse hadron momentum relative to the direction of the incident beam, and the Feynman variable xF.
