Description
D* meson production has been measured in inelastic scattering of 160 GeV/c muons from a 6LiD target with the COMPASS spectrometer at CERN for photon virtualities Q2 in the range 0.003 to10 GeV2, Bjorken-x from
0.00003 to 0.1 and virtual photon energy from 20 to 140 GeV.
The investigation is based on 8100 events where a D0 or Anti-D0 was detected subsequently to a D*+ or D*- decay. The semi-inclusive differential D*+ and D*- production cross sections as a function of D meson energy, transverse momentum, energy fraction z and virtual photon energy and the total visible production cross section are compared with theoretical predictions for the process which is assumed to be due to photon-gluon fusion into open charm.
