Book Description
We report a number of results on beauty production from the D[null] experiment at the Fermilab Tevatron Collider operating at[radical]s= 1.8 TeV. Measurements of the[ital b][ital[anti b]] production cross section using single muon, muon plus jet and dimuon plus jet triggers, in the data collected in 1992-93, are presented. A preliminary measurement of the[ital b][ital[anti b]] angular correlations using the dimuon data sample is also presented. We find that the[ital b]-quark production cross section for[vert-bar][ital Y][sup b][vert-bar][lt] 1.0 and[ital p][sub T][sup b][gt] 8 GeV/c is systematically higher than, although consistent within errors with, the next-to-leading order (NLO) QCD predictions. A similar comparison with QCD is observed in the[ital b][ital[anti b]] ([mu][mu]) angular correlations, where the shape of the distribution indicates a sizable contribution fro the NLO process.

Book Description
The authors present measurements of the b[bar b] production cross section and angular correlations between the b and[bar b]-quarks in p[bar p] collisions using the D0 detector at the Fermilab Tevatron operating at[radical]s= 1.8 TeV. The b-quark production cross section for[vert-bar]y[sup b][vert-bar]1.0 and[rho][sub[tau]][sup b] 8 GeV/c is extracted and found to be consistent with next-to-leading order QCD predictions. In addition, the angular correlations between the b and[bar b]-quarks are found to agree in shape with next-to-leading order QCD predictions.

Book Description
We have studied the[ital J]/[psi] production in[ital p][ital[anti p]] collisions at[radical]s= 1.8 TeV with the D[null] detector at the Fermilab Tevatron, using a[mu][sup+][mu][sup -] data sample collected during the 1994-95 running period. We have measured the inclusive[ital J]/[psi] production cross section as a function of the[ital J]/[psi] transverse momentum, [ital P][sub T][sup[ital J]/[psi]] in the central and forward rapidity regions. The new measurement of the cross section[ital d[sigma]/dp][sub T][sup[ital J]/[psi]] for[vert-bar][eta][sup[ital J]/[psi]][vert-bar][lt] 0.6 is in a good agreement with the CDF and earlier D[null] results. The cross section measurement[ital d[sigma]/dp][sub T][sup[ital J]/[psi]] for 2.5[lt][vert-bar][eta][sup[ital J]/[psi]][vert-bar][lt] 3.7 covers the[ital p][sub T][sup[ital J]/[psi]] range from 1 to 16 GeV/c. We combine the measurements in several[vert-bar][eta][sup[ital J]/[psi]][vert-bar] regions to discuss[ital d[sigma]/d[eta]][sup[ital J]/[psi]] for[ital p][sub T][sup[ital J]/[psi]][gt] 8 GeV/c. The data are compared with the next-to- leading order (NLO) QCD calculations, which take into account different[ital J]/[psi] production mechanisms.

Book Description
Preliminary results on B physics studies from the D0 experiment at the Fermilab collider are presented. Single and dimuon events produced in p[bar p] collisions at [radical]s = 1.8 TeV were used in the analysis. Inclusive single muon and J/[Psi] differential cross sections are shown. The results of a measurement of the time averaged B[sup 0][bar B][sup 0] to mixing parameter are presented.

Book Description
The measurement of the D0 azimuthal anisotropy with respect to the reaction plane indicates that low momentum charm quarks participate in the collective expansion of the high density, strongly interacting medium formed in ultra relativistic heavy ion collisions, despite their large mass. This behavior can be explained by charm hadronization via recombination with light quarks from the medium and collisional energy loss. The measurement of the D0 production in p Pb collisions is crucial to separate the effect induced by cold nuclear matter from the final state effects induced by the hot medium formed in Pb Pb collisions.
