Branching fractions for B̄_s to charmed-strange mesons are predicted in the covariant light-front quark model; the s-wave rates match data, several p-wave channels look observable, and the D'_s1 rate overshoots experiment by about four times.
(6) The explicit form of h′ P is given by h′ P =(M ′2 − M ′2 0) √ x1x2 Nc 1√ 2~M ′ 0 ϕ′, (7) where ϕ′ is the light-front momentum distribution amplitude for an s-wave mes on

Semileptonic and nonleptonic $\bar{B}_{s}\to D_{sJ}$ decays in covariant light-front approach
Branching fractions for B̄_s to charmed-strange mesons are predicted in the covariant light-front quark model; the s-wave rates match data, several p-wave channels look observable, and the D'_s1 rate overshoots experiment by about four times.
