Gh. Arakelyan et Pe. Volkovitsky, CHARMED PARTICLE-PRODUCTION IN HADRON-HADRON COLLISIONS, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 353(1), 1995, pp. 87-101
In the framework of Quark-Gluon-String Model developed recently in ITE
P we calculate spectra of charmed particles D, D-s,Lambda(c),Xi(c),Ome
ga(c) in hadron-hadron collisions taking into account the decays of S-
wave resonances like D,D*(s), Sigma(c),Sigma*(c),Xi*(c),Xi'(c), and O
mega(c). We describe the bulk of the existing data on D, D*, ad Lambd
a(c) production in pi p and pp collisions and predict the yield of cha
rmed particles in Sigma(-)p and Xi(-)p reactions at hyperon beam energ
ies of 340 GeV/c and 600 GeV/c. Because of significant production of b
aryon resonances our predictions for unfavored fragmentation differ fr
om predictions of other models which do not take resonance production
into account.
