Measurement of the production cross-section of positive pions in the collision of 8.9 GeV/c protons on beryllium

HARP Collaboration

The double-differential production cross-section of positive pions, $d^2{\sigma }^{{\pi }^{+}}/dpd\Omega$, measured in the HARP experiment is presented. The incident particles are 8.9 GeV/c protons…
