Spectra of charmed particles produced in νp interactions

Momentum spectra and cross sections of D+, D-, D0 charmed mesons and Λsub(c)sup(+), epsilonsub(c)sup(++) charmed baryons produced in νp interactions are calculated. Charmed hadrons are produced through recombination of the charmed quark produced in the weak subprocess with quark from the initial proton. The recombination process is described phenomenologically in the language of recombination functions. The probability of fragmentation of initial proton to a set of quarks necessary for production of the charmed hadron with the given quantum numbers is assigned by multiparton distribution functions. These functions have been determined in the framework of statistical parton model with Regge asymptotics which satisfies the QCD main positions. Free parameters of multiparton distribution functions have been determined from the analysis of data on the production of charmed hadrons in pp-collisions. The calculated spectra of charmed mesons have a ''soft'' character, the baryonic, on the contrary - a ''hard'' one. The ''hard'' spectrum of charmed baryons produced in νp interactions is specified by a ''hard'' character of Λsub(c)sup(+) spectrum produced in pp-collisions
