Study of Pion Production in νμ Interactions on 40Ar in DUNE Using GENIE and NuWro Event Generators

The study of pion production and the effects final state interactions (FSI) are important for data analysis in all neutrino experiments. For energies at which current experiments being operated, a significant contribution to is made by resonance process. After its production, if absorbed nuclear matter, event may become indistinguishable from quasi-elastic scattering process acts as background. estimation this background very essential oscillation requires good theoretical models both primary vertex after FSI. Due FSI, number pions significantly different produced vertex. As detectors can observe only particles, correct information about particles overshadowed To overcome difficulty, knowledge FSI required be provided incorporated Monte Carlo (MC) generators. In work, we will present simulated events two MC generators - GENIE NuWro, $\nu_{\mu}$CC on $^{40}$Ar target DUNE experimental set up. A brief outline used presented. results presented form tables showing occupancy topologies with 100$\%$ detector resolution kinetic energy threshold cuts. We that NuWro (v-19.02.2) more transparent (less responsive) absorption charge exchange processes compared (v-3.00.06), likely than created during their intranuclear transport there need improve technology better results.
