Abstract
We present a novel lepton-nucleus event generator: ACHILLES, A CHIcagoLand Lepton EventSimulator. The generator factorizes the primary interaction from the propagation of hadrons in thenucleus, which allows for a great deal of modularity, facilitating further improvements and interfaceswith existing codes. We validate our generator against high quality electron-carbon scattering datain the quasielastic regime, including the recent CLAS/e4v reanalysis of existing data. We findgood agreement in both inclusive and exclusive distributions. By varying the assumptions on thepropagation of knocked out nucleons throughout the nucleus, we estimate a component of theoreticaluncertainties. We also propose novel observables that will allow for further testing of lepton-nucleusscattering models. ACHILLES is readily extendable to generate neutrino-nucleus scattering events.
