Υ Production at Hadron Colliders : a Review
We give an overview of the present status of knowledge of the production of J/ψ, ψ′ and Υ in high-energy hadron collisions. We first present two early models, namely the ColourSinglet Model (CSM) and the Colour-Evaporation Model (CEM). The first is the natural application of pQCD to quarkonium production and has been shown to fail dramatically to describe experimental data, the second is its ph...
متن کاملObservation of sequential Υ suppression in PbPb collisions.
The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of 150 μb(-1) and 230 nb(-1), respectively, collected in 2011 by the CMS experiment at the LHC, at a center-of-mass energy per nucleon pair of 2.76 TeV. The Υ(nS) yields are measured from...

متن کاملAssociated Production of Υ and Weak Gauge Bosons in Hadron Colliders
We calculate the rate of production of W + Υ and Z0 + Υ in hadron colliders. We find the cross sections for W + Υ and Z0 + Υ to be roughly 0.45 pb and 0.15 pb at the Tevatron and roughly 4 pb and 2 pb at the LHC. The dominant production mechanism involves the binding of a color-octet bb̄ pair into a P-wave bottomonium state which subsequently decays into Υ. The purely leptonic decay modes of Υ, ...
متن کاملPhotons from axial-vector radiative decay in a hadron gas.
Strange and non-strange axial-vector meson radiative decays contribute to photon production in hadron gas. Oneand two-hadron radiative decay modes of b1(1235), a1(1260) andK1(1270) are studied. At 200 MeV temperature and for a narrow range in photon energies they contribute more to the net thermal photon production rate than πρ → πγ, ππ → ργ or ρ → ππγ. They provide significant contribution to ...
