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

Understand

We analyze the semileptonic $B\to K_2^*(1430)l^+l^-$ 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.
