Computing the nucleon charge and axial radii directly at Q[superscript 2] = 0 in lattice QCD

Computing the nucleon charge and axial radii directly at Q[superscript 2] = 0 in lattice QCD

We describe a procedure for extracting momentum derivatives of nucleon matrix elements on the lattice directly at Q[superscript 2]=0. This is based on the Rome method for computing momentum derivatives of quark propagators. We apply this procedure to extract the nucleon isovector magnetic moment and...
