Analysis of the $\bar{B}\to {\bar{K}}_2(1430){\ell }^{+}{\ell }^{-}$ decay

Abstract

We present an analysis of the decay process $\bar{B}\to {\bar{K}}_2(1430){\ell }^{+}{\ell }^{-}$, where this process has all the features of the related and well investigated process $\bar{B}\to {\bar{K}}^{\ast }(890){\ell }^{+}{\ell }^{-}$, with theoretically comparable branching ratios. The differential decay rate as well as the forward-backward asymmetry are worked out, where the sensitivity of these to possible right-handed couplings for the related $b\to s$ radiative decay are also investigated.
