Hadron Production cross-sections

Hadron production measurements for neutrino experiments is a well established field since the '70s. In recent years, interest in such studies was revived and new generation of low-to-medium energy (from 1 to 100 GeV) hadron production experiments were built or proposed. Such experiments all share a basic design, consisting in the presence of open-geometry spectrometers, capable of - as close as possible - full angular coverage and full particle identification. New results are now provided by Harp; the future will most likely bring more measurements thanks to MIPP and NA49.
