Abstract

We compute the b quark mass from dynamical lattice QCD with clover quarks. The calculation is done at a fixed lattice spacing with sea quark masses as low as half the strange quark mass. Our final result is mb¯(mb¯)=4.25(2)(11)GeV, where the first error is statistical and the last error is the systematic uncertainty.
