We present a relativistic calculation of two-photon decays for heavy and light mesons in the framework of the Salpeter equation for quark-antiquark states. The meson-photon-photon vertex is computed by reconstructing the Bethe-Salpeter vertex function and evaluating the fourdimensional Feynman diagr
We study the decay of the pentaquark baryon in a non-relativistic quark model for positive and negative parity Ξ + states. The decay amplitudes are expressed as products of a spectroscopic factor and an interaction matrix element. It is shown that relatively narrow widths can be obtained for positiv
