Two-photon decay rates of heavy quarkonia in the relativistic quark model

arXiv:hep-ph/0302044 · doi:10.1142/S021773230300971X

Abstract

Two-photon decay rates of pseudoscalar, scalar and tensor states of charmonium and bottomonium are calculated in the framework of the relativistic quark model. Both relativistic effects and one-loop radiative corrections are taken into account. The obtained results are compared with other theoretical predictions and available experimental data.
