J/psi and psi' production and their normal nuclear absorption in proton-nucleus collisions at 400 GeV

NA50 Collaboration

We report a new measurement of J/psi, psi' and Drell-Yan cross-sections, in the kinematical domain $-0.425<y_{\mathrm{cm}}<0.575$ and $-0.5<\cos {\theta }_{\mathrm{CS}}<0.5$, performed at the CERN-SP…
