This analysis aims to study inclusive neutrino-induced Neutral Current (NC) interactions that produce at least one neutral pion (π0) in the final state (incNCπ0 ) in the T2K off-axis near detector ND280. The motivation for this study is to better understand/eliminate the background to electron neutrino appearance analyzed at the far detector Super-Kamiokande. As π0 decays are background to the appearance search, a good knowledge of both inclusive and exclusive neutrino interaction cross sections are key to improving associated systematic uncertainties in T2K oscillation analyses. Results from this study can be compared to a number of Monte Carlo samples produced using different neutrino interaction generators. This could yield information about models of neutrino-nucleon interactions. Further comparisons can be made with the incCCπ0 sample already obtained from a T2K near detector analysis. In this poster, the selection criteria used to collect inclusive neutral current neutrino interactions on plastic scintillator (CH) with at least one π0 in the final state will be presented, including a discussion of how selection criteria were improved. I will also discuss the changes in the selections, including use of a fitting method to improve measurement of the incNCπ0 interaction rate.
