Measurement of di-muons from 400 GeV/c protons interacting in a thick molybdenum/tungsten target
A. Aksoy, R. Albanese, K. Albrecht, F. Alessio et autres
Di-muon events emanating from a replica of the SHiP target at the CERN SPS contain a clear signal of $J/ \psi$ production. The production rate is in reasonable agreement with Monte Carlo based on Pythia v8. For the interval in rapidity defined …
