Abstract
The rare decays [Formula: see text] are important to probe the flavor sector of the standard model and to search new physics beyond the SM. Unlike pseudoscalar [Formula: see text] meson, the leptonic decays of vector [Formula: see text] mesons are not chirally suppressed which compensates for their short lifetimes, and results in significant branching ratios. In this paper, we estimate the branching ratios of [Formula: see text][Formula: see text] rare decays in [Formula: see text] model which is an extension of the SM with an extra [Formula: see text] gauge symmetry. We find that the branching ratios are increased from their corresponding standard model values and vary with the mass of [Formula: see text] boson. The lower the mass of [Formula: see text] boson, the higher is the branching ratio.
