Study of Nuclear Physics for New Physics with Quantum Monte Carlo
Prof. Dr. Garrett King (Los Alamos, USA)

Precision measurements involving nuclei are at the cutting edges of nuclear physics and testing the Standard Model (SM) of physics. For instance, precision beta decay measurements have the potential to constrain beyond SM physics at TeV scales. To interpret these experiments, it is crucial to have comparably accurate theoretical predictions of relevant quantities along with an accurate understanding of the underlying nuclear dynamics. In this contribution, I will overview recent calculations of electroweak processes with quantum Monte Carlo (QMC) computational methods used to solve the many-body Schr ̈odinger equation. The QMC approach retains the complexity of many-nucleon dynamics and provides highly accurate results for light nuclei. I will discuss calculations of observable quantities with readily available data–such as beta decay and electromagnetic reactions–used to validate models of nuclear many-body interactions and electroweak currents. I will present QMC calculations of predicted quantities relevant to on-going beta decay experiments and discuss how these results will impact experimental determinations of beyond standard model physics.
