First results on the longitudinal double spin asymmetry for identified hadrons from the 2011 COMPASS data — •Malte Wilfert — for the COMPASS collaboration — Institut für Kernphysik, Johannes Gutenberg-Universität Mainz, Johann-Joachim-Becher-Weg 45, 55128 Mainz
The COMPASS experiment at the M2 beamline of the CERN SPS has taken data with a polarised muon beam scattering off a polarised NH3 target in 2011. The beam energy has been increased to 200 GeV as compared to 160 GeV in 2007. With the increased beam energy it is possible to reach higher values of Q2 and lower values of x compared to our first measurement in 2007. We will present our results on the longitudinal double spin asymmetry for identified hadrons (A1,pπ± ,A1,pK±). The results will be compared to our previous results from 2007.
