A non-perturbative calculation of the mass of the Bc

We present a calculation of the mass of the 1 S 0 pseudoscalar bc(B c) state using a non-perturbative measurement from quenched lattice QCD. We find M BC = 6.386(9)(98)(15) GeV where the first error is statistical, the second systematic due to the quark mass ambiguities and quenching and the third t...

Summary:We present a calculation of the mass of the 1 S 0 pseudoscalar bc(B c) state using a non-perturbative measurement from quenched lattice QCD. We find M BC = 6.386(9)(98)(15) GeV where the first error is statistical, the second systematic due to the quark mass ambiguities and quenching and the third the systematic error due to the estimation of mass of the η b .
