Abstract
We give a detailed study of the two-gamma decay of some heavy pseudoscalar mesons using the pole-dominance model. The transition matrix elements of PL to bare glueball (G0) are also computed, and it is found that the PL to glueball contribution is comparable with that of PL to π0. From our results, we have obtained the two-gamma decay width of DL and an upper limit of the two-gamma decay widths of BL and BsL mesons.
