Calculation of the derivative of nucleon form factors in Nf = 2 + 1 lattice QCD at Mπ = 138 MeV on a (5.5 fm)3 volume

We present a direct calculation for the first derivative of the isovector nucleon form factors with respect to the momentum transfer q2 using the lower moments of the nucleon 3-point function in the coordinate space. Our numerical simulations are performed using the Nf = 2 + 1 nonperturbatively O(a)...
