Nucleon properties at finite lattice spacing in chiral perturbation theory
Nucleon properties at finite lattice spacing in chiral perturbation theory
Properties of the proton and neutron are studied in partially quenched chiral perturbation theory at finite lattice spacing. Masses, magnetic moments, the matrix elements of isovector twist-2 operators and axial-vector currents are examined at the one-loop level in a double expansion in the light-quark masses and the lattice spacing.
