Measurement of the spin-structure function g 2 and the semi-inclusive double-spin asymmetries at HERMES

  • 1. Institute for High Energy Physics, Protvino (Russian Federation)

Description

A measurement of the virtual-photon asymmetry A 2 and of the spin-structure function g 2 of the proton are presented for the kinematic range of the HERMES experiment carried out at the HERA electron storage ring at DESY. Semi-inclusive longitudinal double-spin asymmetries provide new insight into the valence quark helicity distributions Δu v and Δd v.
