Description

We present preliminary results for nucleon form factors calculated with the plateau method varying the source-sink separation time t_s on a (10.8fm)^4 lattice at the physical point in 2+1 flavor QCD. The configurations are generated with the stout-smeared O(a)-improved Wilson quark action and the Iwasaki gauge action at beta=1.82 corresponding to the lattice spacing of 0.084 fm. We discuss the momentum dependence of the form factors in very small transfer momentum region examining a possible t_s dependence.
