Study of Pion Production in ν_μCC Interactions on O16 Using Different MC Generators

In this report we present simulated event numbers, for various MC generators, for pion production in $ν_μ$ CC reactions on $\nucl{16}{O}$. For the simulation we used four different neutrino interaction generators: GENIE, FLUKA, NEUT, and NuWro, as proposed during the 45th Karpacz Winter School on neutrino interactions. First we give a brief outline of the theoretical models relevant to pion production. We then present results, in the form of tables showing the occupancy of primary and final state pion topologies, for all the generated samples. Finally we compare the results from the different generators and draw conclusions about the similarities and differences. For some of the generators we explore the effect of varying the axial mass parameter or the use of a different nuclear model.
