Abstract

The pion - quark coupling constant (gπq q) and the B-meson - quark coupling constant (gB-qq) have been found in the processes B*- → B-π0 and B*- → B-γ. Their decay widths have been calculated through the direct coupling of π0 and B- with quarks which are static inside B*- meson.

Keywords

B*- → B-π decay; B*- → B-γ decay; decay widths; coupling of p0 and B- with quarks
