A precise determination of the Bc mass from dynamical lattice QCD
Abstract
We perform a precise calculation of the mass of the Bc meson using unquenched configurations from the MILC collaboration including 2+1 flavours of improved staggered quarks. Lattice NRQCD and the Fermilab formalism are used to describe the b and c quarks respectively. We find the mass of the Bc meson to be 6.304(16) GeV
