Nuclei play a crucial role in high-precision tests of the Standard Model and in the search for physics beyond the Standard Model. Without an accurate understanding of nuclei, we cannot meaningfully interpret experimental data, nor can we distinguish signals of new physics from underlying nuclear effects. Experimental programs that address fundamental questions in nuclear physics, fundamental symmetries, and neutrino physics often depend on precise calculations of the electroweak structure and reactions with nuclei. Quantum Monte Carlo methods are used to solve the many-body problem of strongly correlated nucleons. This microscopic approach yields a picture of the nucleus and its interactions with external electroweak probes, such as electrons and neutrinos, where many-nucleon dynamics are critical to accurately explaining experimental data.
In this talk, I will present recent progress in Quantum Monte Carlo calculations of electrons and neutrinos interactions with nuclei across a wide range of energy and momentum transfer and discuss their connections to ongoing experimental efforts.
