Analysis of exclusive (B_s -> D_{s_0} (2317) l nu_l) decay in "full" QCD
  The transition form factors of the semileptonic decay B_s into scalar D_{s_0}(2317) meson is calculated in the framework of 3-point QCD sum rule. The branching ratio is found to be ~10^(-3) for the (B_s -> D_{s_0}(2317) l nu_l) (l=e,mu) decay, and 10^(-4) for the (B_s -> D_{s_0}(2317) tau nu_tau) decay, respectively.
