Charmed Hadrons from Fragmentation and B Decays
Preview AbstractThe fragmentation functions of D0, D±,
, D*o, D*± and 
at 
are measured with a data set of 102.7 fb-1. Fragmentation model parametrizations (Peterson, Kartvelishvili, Collins-Spiller, Lund, and Bowler models) are compared to the data. The data at high x≃1 indicate a contribution of non-perturbative QCD processes.Production of massless charm jets in pp collisions at next-to-leading order of QCD
Preview AbstractWe present predictions for the inclusive production of charm jets in proton–proton collisions at 7 TeV. Several CTEQ parton distribution functions (PDFs) of the CTEQ6.6M type are employed, where two of the CTEQ6.6 PDFs have intrinsic charm. At large enough jet transverse momentum and large jet rapidity, the intrinsic charm content can be tested.
