Charmonium Production in Nucleus-Nucleus Collisions

نویسنده

چکیده

This is a review of theoretical attempts to describe production of heavy quark bound states in nucleus-nucleus collisions, in particular, the relative suppression of J/ψ and ψ production observed in these reactions. The review begins with a survey of experimental data for proton-induced reactions and their theoretical interpretation. The evidence for additional suppression in nucleus-nucleus collisions is discussed and various theoretical models of charmonium absorption by comoving matter are presented and analyzed. The review concludes with suggestions for future research that would help clarify the implications of J/ψ suppression in Pb + Pb collisions observed by the NA50 experiment.

Charm Production in p̄A-Collisions at the Charmonium Threshhold

Abstract. We discuss the production of charmonium states in antiproton-nucleus collisions at the ψ ′ threshold. It is explained that measurements in p̄A collisions will allow to get new information about the strengths of the inelastic J/ψN and ψ N interaction, on the production of Λc and D̄ in charmonium-nucleon interactions and for the first time about the nondiagonal transitions ψ N → J/ψN. The...

Dynamics and Phenomenology of Charmonium Production off Nuclei

Nuclear suppression of charmonium production in proton-nucleus interactions is poorly understood, what restrains our attempts to single out unusual effects in heavy ion collisions. We develop a phenomenological approach, based on the lightcone dynamics of charmonium production, which has much in common with deepinelastic scattering and Drell-Yan lepton pair production. The key observation is th...

Different Nuclear Dependence of J / ψ and ψ ′ Production in p - A and A - p Collisions ∗

While presently available p-A data observe that the nuclear dependence of J/ψ and ψ production is the same within errors, we show that different nuclear dependence of J/ψ and ψ production in the kinematic region uncovered by the present p-A data can be predicted based on two different nuclear absorption scenarios. It is found that the predicted production ratio σ(ψ)/σ(J/ψ) at positive xF in A-p...
