Effect of Z'-mediated flavor-changing neutral current on B decays into Pi Pi

Abstract

We study the effect of -mediated flavor-changing neutral current on the decays. The branching ratios of these decays can be enhanced remarkably in the non-universal model. Our estimated branching ratios are enhanced significantly from their standard model (SM) value. For = 1, the branching ratios are very close to the recently observed experimental values and for higher values of branching ratios are more. Our calculated branching ratios and are also enhanced from the SM value as well as the recently observed experimental values. These enhancements of branching ratios from their SM value give the possibility of new physics.
