BEACH 2010 - IX International Conference on Hyperons, Charm and Beauty Hadrons

Pion Production in the HARP/PS214 experiment at CERN PS

Not scheduled

Aula Magna (Great Hall) (University of Perugia, Italy)

Speaker

Mauro Mezzetto (PD)

Description

Final results for the production of charged forward pions in the angular range 0.025 < theta < 0.250 rad and in the momentum range 0.5 < p < 8.0 GeV/c will be presented together with final results for the production at large angles 0.35 < theta < 2.15 rad and in the momentum range 100 < p < 800 MeV/c. Data have been taken with incident protons or pions in the range 1.5-15 GeV/c with thin Be, C, Al, Cu, Sn, Ta, Pb solid targets, with thick (1 interaction length) C, Ta, Pb solid targets (large angle production) and with N2, O2 cryogenic targets with the large acceptance HARP experiment at CERN PS. For incident pions the presented data represent the first experimental campaign to systematically measure forward pion hadroproduction. Results have been compared with GEANT4 and MARS MonteCarlo simulations and parametrized (for incident protons) for easy use. The results may be useful for simulation of existing neutrino beamlines, atmospheric neutrinos fluxes, extensive air shower (by reducing the uncertainties of hadronic interaction models in the low energy range), for the tuning of available QCD inspired Monte Carlo simulations and for simulation of future Neutrino Factory beamlines.
