Abstract

Relativistic effects in two photon decay of 0-+ quarkonium are investigated with a relativistic phenomenological approach. Comparing with the non-relativistic approximation, the relativistic phenomenological approach gives corrections coming from three sources: [Formula: see text] relative momentum distribution, [Formula: see text] relative energy distribution and description of quark spinors in the meson. These relativistic effects are studied in detail for [Formula: see text] and [Formula: see text] systems.
