Inclusive D∗ Production in γγ Collisions: Including the Single-Resolved Contribution with Massive Quarks
We have calculated the next-to-leading order cross section for the inclusive production of charm quarks as a function of the transverse momentum pT and the rapidity in two approaches using massive or massless charm quarks. For the singleresolved cross section we have derived the massless limit from the massive theory. We find that this limit differs from the genuine massless version with MS fac...
متن کاملInclusive Photoproduction of D∗ Mesons with Massive Charm Quarks
We have calculated the next-to-leading order cross sections for the inclusive production of D mesons in γp collisions at HERA in two approaches using massive or massless charm quarks. The usual massive theory for the direct cross section with charm quarks only in the final state was transformed into a massive theory with MS subtraction by subtracting the mass divergent and additional finite ter...
متن کاملSecondary Production of Massive Quarks in Thrust
We present a factorization framework that takes into account the production of heavy quarks through gluon splitting in the thrust distribution for e+e−→ hadrons. The explicit factorization theorems and some numerical results are displayed in the dijet region where the kinematic scales are widely separated, which can be extended systematically to the whole spectrum. We account for the necessary ...
متن کاملInclusive particle production in pp̄ Collisions
We calculate the inclusive production of charged hadrons in pp̄ collisions to next-to-leading order (NLO) in the QCD improved parton model using a new set of NLO fragmentation functions for charged pions and kaons. We predict transverse-momentum distributions and compare them with experimental data from the CERN Spp̄S Collider and the Fermilab Tevatron. DESY 95-020 TUM-T31-84/95
متن کاملInclusive Heavy-quarkonium Production in Hadronic Collisions∗
We discuss the theory of inclusive production of heavy quarkonium, the comparison between theory and experiment, and the expected nuclear effects in cold nuclear targets. We also present predictions, based on Nonrelativistic QCD (NRQCD), for quarkonium production cross sections in the LHC energy range. We find that nuclear effects in the production cross sections are largely independent of the ...
