Large-angle production of charged pions by 3-12.9 GeV/c protons on beryllium, aluminium and lead targets
Large-angle production of charged pions by 3-12.9 GeV/c protons on beryllium, aluminium and lead targets
Measurements of the double-differential $\pi^{\pm}$ production cross-section in the range of momentum $100 \MeVc \leq p < 800 \MeVc$ and angle $0.35 \rad \leq \theta < 2.15 \rad$ in proton--beryllium, proton--aluminium and proton--lead collisions are presented. The data were taken with the HARP detector in the T9 beam line of …
