Vector meson and axial-vector diquark decay constants

Abstract

We propose a natural generalization to the case of unequal constituent masses of the formula which gives the correct decay constants for vector mesons of the quarkonium type. Within the philosophy where diquarks are used as baryonic constituents, this allows us to evaluate the decay widths for all vector particles both mesons and diquarks to be used later in the calculation of baryon lifetimes.
