Description
In the framework of the heavy quark effective theory, the leading order Isgur-Wise functions relevant to semileptonic decays of the orbitally P-wave excited Bs meson states Bs**, including the newly found narrow Bs1(5830) and Bs2*(5840) states, into the (Ds1(2536), Ds2*(2573)) doublet are calculated from QCD sum rules. With these universal form factors, the decay rates and branching ratios are also estimated. (physics of elementary particles and fields)
