Measurement of the B-meson and b-quark cross sections at sqrt s =1.8 TeV using the exclusive decay B+/--->J/ psi K+/-. Academic Article uri icon

abstract

  • This letter reports the full reconstruction of B mesons through the decay chain BJ/ K, J/+-, using data obtained at the Collider Detector at Fermilab in pp collisions at s =1.8 TeV. This exclusive sample, the first observed at a hadron collider, is then used to measure the B-meson cross section, from which we extract the b-quark cross section. We obtain =2.80.9 (stat) 1.1(syst) b for B- mesons with PT>9.0 GeV/c and rapidity y<1.0. We obtain =6.11.9(stat) 2.4(syst) b, for b quarks with transverse momentum PT>11.5 GeV/c and rapidity ylt;1.0. 1992 The American Physical Society.
