摘要
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.
