Gluon Polarization from Correlated High-pT Hadron Pairs in Polarized l - N Scattering
A. Bravar, D. von Harrach, A. Kotzinian
Abstract
We propose to access the gluon polarization ΔG by measuring the cross section spin-asymmetry in semi-inclusive polarized lepton -- nucleon scattering. The photon-gluon fusion sub-process will be tagged by detecting high-pT correlated hadron pairs in the forward hemisphere. Selecting oppositely charged kaon pairs will allow to suppress the background coming from gluon radiation.
