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.
