Delta G(x) from high p_t hadrons in DIS at a polarised HERA
Abstract
Description
We investigate the possibility to identify photon-gluon fusion (PGF) events in polarised deep inelastic ep scattering, assuming the kinematics of the HERA collider, by a pair of charged high p_t particles. In a Monte Carlo study we find possible selection criteria and show the expected measurable asymmetries. We discuss the sensitivity to $ΔG(x)$ and compare the result to the one obtained using di-jets to tag PGF events.
