Title: Model-independent determination of B c + η c + ν form factors

Abstract

Here, we derive model-independent bounds on the form factors for the decay B + c → η c+ν including full mass effects, i.e., ℓ = e, μ, and τ. The bounds are obtained by using the Boyd-Grinstein-Lebed parametrization for the form factors, and fitting to the preliminary lattice data of the HPQCD Collaboration.

TABLE I TABLE I: Numeric values for the masses employed in this work. The first six masses are experimentally measured. The masses of scalar and vector Bc mesons were determined on the lattice, and only enter the form factors through the Blaschke factors appearing in Eq. (10). The bottom- and charm-quark massesmore » are given in the MS scheme at μ = mb and μ = 3 GeV, respectively. They only explicitly enter our calculations through the heavy-quark spin symmetry relations given in Sec. V, but are also implicitly used in the evaluations of the Χ functions in Eq. (13).« less
