Book Description
Inclusive J/[psi] and [psi](2S) production has been studied in p[bar p] collisions at [radical]s = 1.8 TeV with the Collider Detector at Fermilab. The products of production cross section times the branching fraction of J/[psi]([psi](2S)) to [mu][sup +][mu][sup [minus]] are reported as functions of the J/[psi]([psi](2S)) P[sub T] in the kinematic range P[sub T]> 6 GeV/c and [vert bar][eta][vert bar] [le] 0.5. The products of the integrated cross section times branching fraction and the b-quark production cross section calculated from these values are also reported.

Book Description
Inclusive J/? and?(2S) production has been studied in {bar p}p collisions at √s = 1.8 TeV using the Collider Detector at Fermilab. The products of production cross section times branching fraction have been measured as functions of P{sub T} for J/?(?(2S)) →??− in the kinematic range P{sub T}{sup J/?(?(2S))}> 6 GeV/c and {vert_bar}?{sup J/{psi}({psi}(2S)){vert_bar}} ≤ 0.5. The products of the integrated cross section times branching fraction are calculated and used to obtain an inclusive b-quark production cross section.

Book Description
A measurement of the J/psi and psi(2S) production cross sections in pp collisions at sqrt(s)=7 TeV with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 inverse picobarns. Using a fit to the invariant mass and decay length distributions, production cross sections have been measured separately for prompt and non-prompt charmonium states, as a function of the meson transverse momentum in several rapidity ranges. In addition, cross sections restricted to the acceptance of the CMS detector are given, which are not affected by the polarization of the charmonium states. The ratio of the differential production cross sections of the two states, where systematic uncertainties largely cancel, is also determined. The branching fraction of the inclusive B to psi(2S) X decay is extracted from the ratio of the non-prompt cross sections to be: BR(B to psi(2S) X) = (3.08 +/- 0.12(stat.+syst.) +/- 0.13(theor.) +/- 0.42(BR[PDG])) 10-̂3.

Book Description
The authors report the latest results on the measurement of inclusive b quark and heavy quarkonium production by the DO collaboration in p[anti p] collisions at[radical]s= 1.8 TeV at the Fermilab Tevatron Collider. The results are from analyses of the 1992--93 data. This report includes measurements of inclusive b quark, J/[psi] and[Upsilon] meson production cross sections. The b quark production cross section, measured in inclusive muon data, is consistent with next to leading order QCD predictions within theoretical and experimental errors. They study J/[psi] and[Upsilon] meson production in dimuon events and perform an investigation of the J/[psi] production mechanisms. Including the latest developments in charmonium phenomenology, the J/[psi] production rates are now almost all accounted for in the transverse momentum range above 8 GeV/c. The observed[Upsilon] production rates, however, are higher than expected by a factor five.

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.
