Exclusive $B --> π\ell^+ \ell^-$ and $B --> ρ\ell^+ \ell^-$ Decays in the Universal Extra Dimension
Abstract
We investigate the influence of the universal extra dimension on the branching ratio in the $B \to π(ρ) \ell^+ \ell^-$ decay. Taking $1/R\sim \{200-1000\}$GeV with one universal extra spatial dimension, which is consistent with the experimental data for ${\cal B}(B \to X_s γ) $, ${\cal B}(B \to K^\ast μ^+μ^- $) and the electroweak precision tests, we obtain that for both ($μ,τ$) channels the branching ratio strongly depends on the compactification radius 1/R.
