چکیده

We describe calculations of cc production to next-to-next-to-leading order (NNLO) and next-to-next-to-leading logarithm (NNLL) near threshold in pp and πp interactions. We study the relevance of these calculations for existing cc total cross section data by examining their sensitivity to partonic threshold kinematics, their convergence properties and scale dependence.

Threshold corrections in bottom and charm quark hadroproduction at next-to-next-to-leading order

We calculate threshold soft-gluon corrections to total cross sections and transverse momentum distributions for bottom and charm quark production in fixed-target experiments, considering both pp and π−p interactions. We investigate the quality of the near threshold soft-gluon approximation at next-to-leading order (NLO) and calculate next-to-nextto-leading order (NNLO) corrections through next-...

Hadroproduction of Charm and Beauty A

Recent results on the hadroproduction of charm and beauty are discussed in the context of the current theoretical and experimental status. The areas covered include production of open charm and beauty particles and charm and beauty quarkonia. Experimental results from both fixed target and colliding beam experiments are presented and compared to theoretical predictions. Predictions based on QCD...

Strangeonium Spectroscopy at the J/G: A Comparison with Kaon Hadroproduction*

An experimental program to study strangeonium mesons produced in the decays of the J/ll, at a r-charm factory is compared with experiments on similar final states in kaon hadroproduction. The sample sizes and experimental performance required are discussed. The complementarity of different production modes and the importance of a broad programmatic approach to this physics are stressed. Present...

Lepton fluxes from atmospheric charm revisited

We update predictions for lepton fluxes from the hadroproduction of charm quarks in the scattering of primary cosmic rays with the Earth’s atmosphere. The calculation of charm-pair hadroproduction applies the latest results from perturbative QCD through next-to-next-to-leading order and modern parton distributions, together with estimates on various sources of uncertainties. Our predictions for...
