| contents | 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. |
