Rare radiative B decay to the orbitally excited [formula omitted] meson

Abstract

The exclusive rare radiative B meson decay to the orbitally excited tensor K 2 ∗(1430) meson is investigated in the framework of the relativistic quark model based on the quasipotential approach in quantum field theory. The calculated branching ratio BR(B→K 2 ∗(1430)γ)=(1.7±0.6)×10 −5 as well as the ratio BR(B→K 2 ∗(1430)γ)/BR(B→K ∗(892)γ)=0.38±0.08 is found in a good agreement with recent experimental data from CLEO.
