Description
Assessing the effect of nuclear and hadronic uncertainty on the interpretation of experimental data is of fundamental importance for electron and neutrino experiments.
Traditionally, Quantum Monte Carlo calculations of lepton-nucleus scattering have been limited to inclusive processes, and are usually limited to A<=12 systems.
I will discuss the short time approximation, a factorization scheme that can extend the reach of first-principle many-body QMC calculations while consistently retaining two-body physics, both in two-body currents and correlations. I will present calculations of electromagnetic response densities and functions in the quasielastic regime, along with the corresponding cross sections, and discuss recent progress in the inclusion of relativistic effects.
