RADIATIVE AND LEPTONIC DECAY OF MESONS
Abstract
Radiative and leptonic decay mesons consisting from heavy and light quarks are considered. The transition matrix element from an initial state to a final state taking into account the relativistic corrections are determined. The widths of Е1 transitions and leptonic decays of mesons consisting of light and heavy quarks is defined.
