Measurement of resonance production in pion-carbon interactions at 158 and 350 GeV/c with NA61/SHINE — •Alexander Herve for the NA61/SHINE collaboration — KIT, Karlsruhe, Germany
The interpretation of extensive air shower measurements, produced by ultra-high energy cosmic rays, relies on the correct modelling of the hadron-air interactions that occur during the shower development. The majority of hadronic particles is produced at equivalent beam energies below the TeV range.
NA61/SHINE is a 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, at 158 and 350 GeV/c, to give precise particle production measurements for the most numerous projectile in air showers, the π meson. The ability to measure the production of resonances, such as the ρ0 and ω mesons, is particularly important to predict the number of muons produced in air showers.
In this contribution we present updated results of resonance spectra at 158 and 350 GeV/c measured by NA61/SHINE.
