We estimate differential rapidity cross sections for $\Psi$ and $\Upsilon$ production via p-Pb collisions at 8 TeV. We use the mixed heavy quark hybrid theory in which the $J/\Psi(1S),\Upsilon(1S),\Upsilon(2S)$ are standard mesons while the…
We estimate differential rapidity cross sections for $J/\Psi$, $\Psi(2S)$, $\Upsilon(1S)$, $\Upsilon(2S)$, and $\Upsilon(3S)$ production via Pb-Pb collisions at proton-proton energy $\equiv \sqrt{s_{pp}}$ =5.02 TeV. For the $\Psi(2S)$,…
We estimate differential rapidity cross sections for $J/\Psi$, $\Psi(2S)$, $\Upsilon(1S)$, $\Upsilon(2S)$, and $\Upsilon(3S)$ production; and $\Psi(2S)$ to $J/\Psi(1S)$, $\Upsilon(3S)$ to $\Upsilon(1S)$ suppression via Xe-Xe collisions at…
We estimate differential rapidity cross sections for $J/\Psi$ and $\Upsilon(1S)$ production via Cu-Cu and Au-Au collisions at RHIC, and the relative probabilities of $\Psi'(2S)$ to $J/\Psi$ production via p-p collisions using our recent…
We estimate the relative probabilities of $\Psi'(2S)$ to $J/\Psi$ production at BNL-RHIC and $\Upsilon(nS)$ production at the LHC and Fermilab in p-p collisions, using our recent theory of mixed heavy quark hybrids, in which the $\Psi'(2S)$…
We present a formalism for determining the cross section for exclusive heavy vector meson production ($J/\psi, \Upsilon$) as a function of rapidity, in both high energy proton-proton and proton-heavy ion collisions, at next-to-leading order…
Differential production cross sections of J/$\psi$ and $\psi$(2S) charmonium and $\Upsilon$(nS) (n = 1, 2, 3) bottomonium states are measured in proton-proton collisions at $\sqrt{s} =$ 13 TeV, with data collected by the CMS detector at the…
The production of J/psi and Upsilon mesons in pp collisions at sqrt(s) = 8 TeV is studied with the LHCb detector. The J/psi and Upsilon mesons are reconstructed in the mu+mu- decay mode and the signal yields are determined with a fit to the…
This brief report is an extension of a previus publication on $\Psi(2S)$ to $J/\Psi(1S)$ suppression in p-Pb collisions at 5.02 TeV to estimate $\Psi(2S)$ to $J/\Psi(1S)$ and $\Upsilon(3S)$ to $\Upsilon(1S)$ suppression via p-Pb collisions…
The production of J /{\psi} and {\Upsilon} mesons is studied in pp collisions at \surds = 7 TeV with the CMS experiment at the LHC. The J /{\psi} measurement is based on a dimuon sample corresponding to an integrated luminosity of 314…
We have performed a systematic study of J/$\psi$ and $\psi$(2S) production in p--p collisions at different Large Hadron Collider (LHC) energies and at different rapidities using the leading order non-relativistic quantum chromodynamics…
CDF has obtained new results on quarkonium production in p\bar{p} collisions at \sqrt{s} = 1.8 TeV. We report on measurements of Upsilon meson production, Upsilon(1S) production from Chi_b feeddown, and the production polarization of…
This article reports on the inclusive production cross section of several quarkonium states, $\mathrm{J}/\psi$, $\psi {\rm (2S)}$, $\Upsilon\rm(1S)$, $\Upsilon\rm(2S)$, and $\Upsilon\rm(3S)$, measured with the ALICE detector at the LHC, in…
The production of Upsilon(1S), Upsilon(2S) and Upsilon(3S) mesons in proton-proton collisions at the centre-of-mass energy of sqrt(s)=7 TeV is studied with the LHCb detector. The analysis is based on a data sample of 25 pb-1 collected at…
This is a continuation of recent studies of $\Upsilon(nS)$ production at the LHC in p-p collisions. Our previous studies were for 2.76 TeV, while the present predictions are for 7.0 TeV collisions.
We report on the inclusive production cross sections of J/$\psi$, $\psi$(2S), $\Upsilon$(1S), $\Upsilon$(2S) and $\Upsilon$(3S), measured at forward rapidity with the ALICE detector in pp collisions at a center-of-mass energy $\sqrt{s}=8$…
This is a continuation of recent studies of $\Upsilon(nS)$ production at the LHC in pp collisions. Our previous studies were for rapidity y=-1 to 1 for the CMS detector, while the present study is for y=2.5 to 4.0 at the LHC.
We calculate the cross section for hadroproduction of a pair of heavy quarks in a 3S1 color-singlet state at next-to-leading order in QCD. This corresponds to the leading contribution in the NRQCD expansion for J/psi and Upsilon production.…
The production of $\Upsilon$(2S) and $\Upsilon$(3S) mesons in lead-lead (PbPb) and proton-proton (pp) collisions is studied in their dimuon decay channel using the CMS detector at the LHC. The $\Upsilon$(3S) meson is observed for the first…
We estimate the energy of the lowest Charmonium and Upsilon states with hybrid admixtures using the method of QCD Sum Rules. Our results show that the $\Psi'(2S)$ and $\Upsilon(3S)$ states both have about a 50% admixture of hybrid and meson…
