Inclusive semileptonic <i>B</i><SUP>0</SUP>_<i>s</i>meson decays at the LHC via a sum-of-exclusive modes technique: possibilities and prospects

We propose an approach for measuring the moments of the hadronic invariant mass distribution in semileptonic B-s(0) meson decays using a sum-of-exclusive technique. Using the present and foreseen knowledge about exclusive semileptonic B-s(0) decays, we estimate the uncertainties on moments of the kinematic distribution. Semileptonic B-s(0) decays can be described, as their B-0 counterpart, using the Heavy Quark Expansion (HQE), with the only difference between the B(s )(0)and B-0 mesons being the SU(3)(F) breaking effects that change the numerical values of the non-perturbative HQE parameters. We extract the HQE parameters for the B-s(0) decays from our estimates of the moments, showing the potential of the proposed method. We identify a set of required measurements for a future precision measurement.
