Quarkonium two-photon decays in QCD

Technical Report:

Abstract

The two-photon decay of tensor charmonium {chi}{sub c2} {yields} 2 {gamma} is calculated with account of gluon condensate effects. The result is in good agreement with experiment. The two-photon width of pseudoscalar b-quarkonium {eta}{sub b} {yields} 2 {gamma} is estimated. 19 refs.; 1 fig.; 1 tab.
