B(s) → Ds0*(2317)P(V) decays in perturbative QCD approach

In this work, we use the pQCD approach to calculate 20 B-(s) -> D-s0*(2317)P(V) two body decays by assuming D-s0*(2317) as a (c) over bars scalar meson, where P(V) denotes a pseudoscalar (vector) meson. These B((s) )decays can serve as an ideal platform to probe the valuable information on the inner structure of the charmed-strange meson D-s0*(2317), and to explore the dynamics of strong interactions and signals of new physics. These considered decays can be divided into two types: the Cabibbo-Kobayshi-Maskawa favored decays and the Cabibbo-Kobayshi-Maskawa suppressed decays. The former arc induced by a b -> c transition, whose branching ratios are larger than 10(-5). The branching fraction of the decay (B) over bar (0)(s) -> D-s0*(+) (2317)rho(-) is the largest and reaches about 1.8 x 10(-3), while the branching ratios for the decay in (B) over bar (0)(s) -> D-s0*(+)(2317)K*( -) and the other two pure annihilation decays (B) over bar (0) -> D-s0*(+)(2317)K-, D-s0*(+)(2317)K*(-) are only at 10(-5) order. Our predictions are consistent well with the results given by the light cone sum rules approach. These decays are most likely to be measured at the running LHCb and the forthcoming SuperKEKB. The latter are induced by a b -> u transition, among which the channel (B) over bar (0) -> D*(-)(2317)rho(+) has the largest branching fraction, reaching up to 10(-5) order. Again the pure annihilation decays B--> D-s0*(-)(2317)phi, (B) over bar (0) -> D-s0*(+)(2317)K+(K*(+)), and B--> D-s0*(-)(2317)K-0(K*(0)) have the smallest branching ratios, which drop to as low as 10(-10) similar to 10(-8).
