Inclusive J/psi Meson Production at D-Zero
Abstract
We present results on inclusive J/psi and b-quark production in pp collisions at sqrt{s} = 1.8 TeV. The results are based on data collected at the DO Experiment during the 1992-1993 FermiLab collider run. There is excellent agreement between the differential J/psi cross section measured at DO and that measured at the CDF detector. A measurement of the fraction of Jpsi events due to b-quark decays is presented and we extract from this a measurement of the integrated b-quark cross section. The radiative decays of chi_{c} charmonium states into the J/psi is discussed and we present results on the fraction of Jpsi mesons that are due to chi_ {c} decays. We also observe that a fraction of promptly produced Jpsi mesons is larger than the measured fraction of Jpsi s due to chi_{c} decays and is not accounted for by existing charmonium production models.
