Description
The MINERvA experiment was designed to measure neutrino-nucleus interactions using the NuMI beam at Fermilab. Between 2013 and 2017, 12x10^20 protons on target were delivered both in neutrino and antineutrino modes with an average neutrino energy of 6 GeV, providing a high statistics neutrino interaction data sample. Among neutrino interactions, a significant primary charged current process is pion production. While charged pions can be detected by ionisation-induced scintillation, as neutral particles, π0 can only be detected from their decay into two photons producing two separate gamma showers. The reconstructed gammas are then used to reconstruct the π0 kinematics. This talk will present the different neutral pion analyses in the MINERvA scintillator tracker, as well as passive iron and lead targets with <Eν> at 6 GeV. This talk will also present a machine learning based semantic segmentation gamma selection, relying on the high statistics of the plastic scintillator.
