Charmonium Production ∗
Theoretical analyses of the results on quarkonium production at large transverse momentum (p T) in p¯ p collisions, at the Tevatron have revealed two novel features of the physics of quarkonium production : 1) the contribution of fragmentation of gluons and charm quarks to the cross-section at large p T , and 2) the importance of colour octet components of the quarkonium wave-function. I discus...
متن کاملInclusive Charmonium Production via Double cc̄ in e+e− Annihilation
Motivated by the recent observation of double charm quark pair production by the Belle Collaboration, we calculate the complete O(αs) inclusive production cross sections for ηc, J/ψ, and χcJ(J=0, 1, 2) plus cc̄ in e +e− annihilation through a virtual photon. We consider both color-singlet and color-octet contributions, and give the analytical expressions for these cross sections. The complete co...
متن کاملDouble charmonium production at B factories within light cone formalism
This report is devoted to the study of the processes e + e − → J/Ψη c , J/Ψη c , ψ η c , ψ η c within light cone formalism. It is shown that the results of the calculation of the cross sections of these processes are in agreement with Belle and BaBar experiments. It is also shown that relativistic and radiative corrections to the cross sections play crucial role in the achievement of the agreem...
متن کاملCharmonium Production and Corona Effect
We study the centrality dependence to be expected if only charmonium production in the corona survives in high energy nuclear collisions, with full suppression in the hot, deconfined core. To eliminate cold nuclear matter effects as far as possible, we consider the ratio of charmonium to open charm production. The centrality dependence of this ratio is found to follow a universal geometric form...
متن کاملcharmonium production at the Tevatron
The production of the P1 charmonium state, hc, at large-pT at the Tevatron is considered. The colour-octet contributions to this state are found to be dominant and give a reasonably large rate for the production of hc. This should make it feasible to look for this resonance in the J/ψ + π decay channel. This production rate is a prediction of NRQCD, and the observation of the hc at the Tevatron...
