Measurement of D0, D+, Ds+ and D*+ production in fixed target 920 GeV proton–nucleus collisions
EUROPEAN PHYSICAL JOURNAL C(2007)
摘要
The inclusive production cross sections of the charmed mesons D-0,D+,D-s(+) and D*(+) have been measured in interactions of 920 GeV protons on C, Ti, and W targets with the HERA-B detector at the HERA storage ring. Differential cross sections as a function of transverse momentum and Feynman's x variable are given for the central rapidity region and for transverse momenta up to p(T)=3.5 GeV/c. The atomic mass number dependence and the leading to non-leading particle production asymmetries are presented as well.
