Abstract :
The exclusive rare radiative B meson decay to the orbitally excited tensor K2∗(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→K2∗(1430)γ)=(1.7±0.6)×10−5 as well as the ratio BR(B→K2∗(1430)γ)/BR(B→K∗(892)γ)=0.38±0.08 is found in a good agreement with recent experimental data from CLEO.
