Description	The production of D* and D mesons in inelastic scattering of 160 GeV/c muons off a (LiD)-Li-6 target has been investigated with the COMPASS spectrometer at CERN for 0.003 (GeV/c)(2) < Q(2) < 10 (GeV/c)(2) and 3 x 10(-5) < x(Bj) < 0.1. The study is based on 8100 events where a D-0 or (D) over bar (0) is detected subsequently to a D(+) or D(-) decay, and on 34000 events, where only a D-0 or (D) over bar (0) is detected. Kinematic distributions of D, D and K-2 (1430) are given as a function of their energy E, transverse momentum p(T), energy fraction z, and of the virtual photon variables nu, Q(2) and x(Bj). Semi-inclusive differential D* production cross-sections are compared with theoretical predictions for D* production via photon-gluon fusion into open charm. The total observed production cross-section for D(+/-) mesons with laboratory energies between 22 and 86 GeV is (1.9 +/- 0.4) nb. Significant cross-section asymmetries are observed between D(+) and D(-) production for nu < 40 GeV and z > 0.6.
