| dc.description.abstract | We present lattice QCD calculations of nucleon electromagnetic form factors using pion masses m[subscript π] = 149, 202, and 254 MeV and an action with clover-improved Wilson quarks coupled to smeared gauge fields, as used by the Budapest-Marseille-Wuppertal Collaboration. Particular attention is given to the removal of the effects of excited-state contamination by calculations at three source-sink separations and the use of the summation and generalized pencil-of-function methods. The combination of a calculation at the nearly physical mass m[subscript π] = 149 MeV in a large spatial volume (m[subscript π]L[subscript s] = 4.2) and the removal of excited-state effects yields agreement with experiment for the electric and magnetic form factors G[subscript E](Q[superscript 2]) and G[subscript M](Q[superscript 2]) up to Q[superscript 2] = 0.5 GeV[superscript 2]. | en_US |
