Study of new physics effects in B ¯ s → D s ∗ τ − ν ¯ τ $$ {\overline{B}}_s\to {D}_s^{\left(\ast \right)}{\tau}^{-}{\overline{\nu}}_{\tau } $$ semileptonic decays using lattice QCD form factors and heavy quark effective theory
Abstract We benefit from the lattice QCD determination by the HPQCD of the Standard Model (SM) form factors for the B ¯ s → D s $$ {\overline{B}}_s\to {D}_s $$ [Phys. Rev. D 101 (2020) 074513] and the SM and tensor ones for the B ¯ s → D s ∗ $$ {\overline{B}}_s\to {D}_s^{\ast } $$ ( arXiv:2304.03137...
