Study of ρ0 production in pion-carbon interactions with NA61/SHINE. — •Alexander Herve for the NA61/SHINE collaboration — KIT Karlsruhe
NA61/SHINE is an fixed target experiment at the CERN Super Proton Synchrotron, studying hadron production in hadron-nucleus and nucleus-nucleus collisions to provide valuable contributions to a number of subjects, from neutrino through cosmic-ray to heavy-ion physics.
Pion-Carbon interactions have been performed to give precise particle production measurements for the most numerous projectile in air showers, the π meson. The ability to measure the production of ρ0 mesons is particularly important to predict the number of muons produced in air showers.
Experimentally, the ρ0s can be measured by studying the invariant mass distribution, which is calculated by combining all possible pairings of tracks from an event. This also leads to a combinatorial background, which can be estimated by two different methods, event mixing and charge mixing.
In this contribution, we present an analysis of simulated data to demonstrate the performance of these two methods.
