Müller (HPQCD Collaboration) We give results for the Upsilon spectrum from lattice QCD using an improved version of the nonrelativistic QCD action for b quarks which includes radiative corrections to kinetic terms at O ( v 4 ) in the velocity expansion. We also include for the first time the effect of up, down, strange and charm qu... [Phys. Rev. D 85, 054509] Published Wed Mar 21, 2012
