Quantum Monte Carlo Calculations of Magnetic Moments for A ≤ 10 Nuclei

ORAL

Abstract

Searches for new physics in experiments such as precision beta decay measurements, neutrinoless double beta decay, and neutrino oscillation experiments will feature electroweak phenomena. These experiments require input from theory, and an accurate understanding of nuclear dynamics is needed to extract new physics. In particular, an accurate electromagnetic current and an understanding of model dependencies is vital for this effort. We report Quantum Monte Carlo calculations of magnetic form factors and magnetic moments for A ≤ 10 nuclei using the Norfolk two- and three-nucleon (NV2+3) chiral interactions and one- and two-body electromagnetic currents. We use low-energy constants (LECs) to parameterize these currents up to next-to-next-to-next-to leading order (N3LO). The form factor calculations show agreement with data even in the high momentum transfer region at N3LO. Additionally, the magnetic moment calculations agree with data for both models considered.
