Abstract

We present an analysis of semileptonic decays of orbitally, P-wave excited B_s meson states B_s^**, including the newly found narrow B_s1(5830) and B_s2^*(5840) states, into low-lying D_s mesons (D_s(1968), D_s^*(2112), D_sJ(2317), D_sJ(2460)) within the framework of the heavy quark effective theory. The relevant universal form factors are estimated using QCD sum rules at the leading order of the heavy quark expansion. The decay widths are predicted and the branching ratios are estimated.
