Analysis of gluon polarisation for single hadron production with high-pT hadrons in the low Q2
Abstract
We present recent COMPASS result on gluon polarisation. We recently analysed longitudinal double spin asymmetry ALL (pT) for single hadron production with high-pT hadrons in the low Q2 regime using all COMPASS data. LiD and NH3 were used as polarized deuteron and proton targets. The asymmetries, which are almost consistent with zero, are compared to theoretical predictions with various ΔG hypotheses.
