Decay constant of $$B_s$$ Bs and $$B^*_s$$ Bs∗ mesons from $$\mathrm{N_f}=2$$ Nf=2 lattice QCD
Abstract We report on a two-flavor lattice QCD estimate of the $$B_s$$ Bs and $$B^*_s$$ Bs∗ leptonic decays parameterized by the decay constants $$f_{B_s}$$ fBs and $$f_{B^*_s}$$ fBs∗ . In addition to their relevance for phenomenology, their extraction has allowed us to investigate whether the “step...
