摘要：

Using a silicon-microstrip detector array to identify secondary vertices, we have observed bJ/+- decays in 800 GeV/c proton-gold interactions. The doubly differential cross section for J/ mesons originating from b-quark decays, assuming linear dependence on nucleon number, is d 2/dxF dpT2=1072819 [pb/(GeV/c)2]/nucleon at xF=0.05 and pT=1GeV/c. This measurement is compared to next-to-leading-order QCD predictions. The integrated b-quark production cross section, obtained by extrapolation over all xF and pT, is (pNbb+X)=5.71.51.3 nb/nucleon. © 1995 The American Physical Society.
