Title: Effect of Z Prime -mediated flavor-changing neutral current on B {yields} {pi}{pi} decays

Abstract

We study the effect of Z Prime -mediated flavor-changing neutral current on the B {yields} {pi}{pi} decays. The branching ratios of these decays can be enhanced remarkably in the nonuniversal Z Prime model. Our estimated branching ratios B(B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}) are enhanced significantly from their standard model (SM) value. For g Prime /g = 1, the branching ratios B(B{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}) are very close to the recently observed experimental values and for higher values of g Prime /g branching ratios are more. Our calculated branching ratios B(B{sup 0} {yields} {pi}{sup +}{pi}{sup -}) and B(B{sup +} {yields} {pi}{sup +}{pi}{sup 0}) 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.
