Magnetic moments for \(A \le 3\) nuclei from chiral effective field theory

ORAL

Abstract

We present recent no-core shell model (NCSM) calculations of magnetic moments in \(A \le 3\) nuclei with chiral-EFT improved M1 operator and LENPIC interactions. We have derived the M1 operator from chiral-EFT electromagnetic currents up to N2LO in power counting, including two-body pion-exchange terms. We focus the discussion on the corrections that arise from the two-body pion-exchange terms, the convergence with respect to the NCSM basis space parameters, and the impact of coordinate space regulators.
