Factorized Calculations for Particle Interactions in Nuclei

This paper proposes a factorized approach to calculate nuclear currents, simplifying calculations for electron, neutrino, and beyond Standard Model (BSM) processes. The factorization separates nucleon dynamics from nuclear wave function overlaps, enabling efficient computation and flexible modification of nucleon couplings. This is particularly relevant for event generators used in neutrino physics and other areas where accurate modeling of nuclear effects is crucial.
