Measurement of Asymmetries in high-pT Single Hadron Production at COMPASS † — •R. Kuhn, A.-M. Dinkelbach, J. M. Friedrich, S. Gerassimov, B. Grube, B. Ketzer, I. Konorov, T. Nagel, S. Paul, L. Schmitt, P. Tunka, and Q. Weitzel — Technische Universität München, Physik-Department E18
During the three beamtimes 2002–2004 COMPASS has measured hard scattering processes of polarized muons off a polarized 6LiD target. The spin asymmetry of the hadron production cross section at high transverse momenta is related to the polarized gluon density Δ G of the nucleon. An update on the analysis of this asymmetry for single hadrons at low Q2 and small xBj will be presented.
