Abstract

The transition form factors of the semileptonic decay B-s into scalar D-s0(2317) meson is calculated in the framework of 3-point QCD sum rule. The branching ratio is found to be similar to 10(-3) for the B-s -> D-s0(2317)center dot(v) over bar (center dot)(center dot=e,mu) decay, and similar to 10(-4) for the B-s -> D-s0(2317)tau(v) over bar (tau) decay, respectively.
