Nucleons in Two-Flavor Partially-Quenched Chiral Perturbation Theory
Silas R. Beane🇺🇸 · Martin J. Savage🇺🇸
Abstract
Properties of the proton and the neutron are explored in partially-quenched chiral perturbation theory with two non-degenerate light flavors. Masses, magnetic moments, matrix elements of isovector twist-2 operators and axial-vector currents are computed at the one-loop level in the chiral expansion.
