B to strange tensor meson transition in a model with one universal extra dimension

Abstract

We analyze the semileptonic $B\to K_2^{\ast }(1430)l^{+}{l}^{-}$ transition in universal extra dimension model. In particular, we present the sensitivity of related observables such as branching ratio, polarization distribution and forward-backward asymmetry to the compactification factor (1/R) of extra dimension. The obtained results from extra dimension model show overall a considerable deviation from the standard model predictions for small values of the compactification factor. This can be considered as an indication for existence of extra dimensions.
