Charmonium from Lattice QCD
Charmonium is an attractive system for the application of lattice QCD methods. While the sub-threshold spectrum has been considered in some detail in previous works, it is only very recently that excited and higherspin states and further properties such as radiative transitions and two-photon decays have come to be calculated. I report on this recent progress with reference to work done at Jeff...
متن کاملPerturbative QCD forbidden charmonium decays and gluonia.
We address the problem of observed charmonium decays which should be forbidden in perturbative QCD. We examine the model in which these decays proceed through a gluonic component of the J/Ψ and the ηc, arising from a mixing of (cc̄) and glueball states. We give some bounds on the values of the mixing angles and propose the study of the pp̄ → φφ reaction, at √s ≃ 3 GeV, as an independent test of t...
متن کاملHybrid charmonium from lattice QCD∗
We review our recent results on the J PC = 0 −− exotic hybrid charmonium mass and J PC = 0 −+ , 1 −− and 1 ++ nonexotic hybrid charmonium spectrum from anisotropic improved lattice QCD and discuss the relevance to the recent discovery of the Y (4260) state and future experimental search for other states.
متن کاملColorless States in Perturbative QCD : Charmonium and Rapidity
We point out that an unorthodox way to describe the production of rapid-ity gaps in deep inelastic scattering, recently proposed by Buchm uller and Hebecker, suggests a description of the production of heavy quark bound states which is in agreement with data. The approach questions the conventional treatment of the color quantum number in perturbative QCD.
