Abstract
We study the effect of both Z and Z'-mediated flavor-changing neutral currents (FCNCs) on the rare decay. We find the branching ratio is reasonably enhanced from its standard model value due to the effect of both Z and Z'-mediated FCNCs, and gives the possibility of new physics beyond the standard model. The contribution of Z'-boson depends upon the precise value of the mass of Z' boson.
