Analysis of the $ {B}_{(s)}\to T({J}^{P}={2}^{-})$ transition in light cone QCD sum rules

The semileptonic $ {B}_{(s)}\to T({J}^{P}={2}^{-}){l}^{+}{l}^{-}$ decays induced by flavor changing neural currents are investigated within the light cone quantum chromodynamics (QCD) sum rule method in the leading order of $ O({\alpha }_{s})$. We apply the $ B$ meson distribution amplitudes up to twist-4 and calculate the relevant form factors of the $ {B}_{(s)}\to T$ transitions, where $ T={K}_{2},{a}_{2},{f}_{2},{\varphi }_{2}$ with $ {J}^{P}={2}^{-}$. The obtained results of the form factors then adopted in the calculations of the corresponding widths. The present results can be used in future experiments for studying the properties of $ {J}^{P}={2}^{-}$ tensor mesons.
