Résumé

The mid-rapidity (d σ_{p N} / d y at y = 0) and total (σ_{p N}) production cross sections of Jψ mesons are measured in proton-nucleus interactions. Data collected by the HERA-B experiment in interactions of 920 GeV / c protons with carbon, titanium and tungsten targets are used for this analysis. The Jψ mesons are reconstructed by their decay into lepton pairs. The total production cross section obtained is σ_{p N}^{J / ψ} = 663 ± 74 ± 46 nb / nucleon. In addition, our result is compared with previous measurements.

N2 - The mid-rapidity (d σp N / d y at y = 0) and total (σp N) production cross sections of Jψ mesons are measured in proton-nucleus interactions. Data collected by the HERA-B experiment in interactions of 920 GeV / c protons with carbon, titanium and tungsten targets are used for this analysis. The Jψ mesons are reconstructed by their decay into lepton pairs. The total production cross section obtained is σp NJ / ψ = 663 ± 74 ± 46 nb / nucleon. In addition, our result is compared with previous measurements.
