摘要：

In this report, recent results from the HERA-B experiment on heavy flavour production in proton-nucleus interactions using a 920 GeV proton beam are presented. The topics include the production of the charmonium states J/psi, psi and chi(c) of the D-meson states D-0, D+/-, D*, the open beauty production cross section (b (b) over bar production) and the Y production cross section. The nuclear dependence for the differential cross sections of charmonium production is discussed. The results are mainly preliminary. The report closes with a summary of the HERA-B search for pentaquark states with strangeness, which yielded quite stringent upper limits for the production of such states in hadronic environments.
