Doser The polarization of inclusive J/ψ and Υ(1S) produced in Pb–Pb collisions at √sNN = 5.02 TeV at the LHC is measured with the ALICE detector. The study is carried out by reconstructing the quarkonium through its decay to muon pairs in the rapidity region 2.5 < y < 4 and measuring the polar and azimuthal angular distributions of the muons. The… Expand

Perspectives for quarkonium studies at the high-luminosity LHC
We review the prospects for quarkonium-production studies in proton and nuclear collisions accessible during the upcoming phases of the CERN Large Hadron Collider operation after 2021, including theExpand


Polarization of prompt J / ψ at the Fermilab Tevatron
The polarization of prompt $J/\ensuremath{\psi}$ at the Fermilab Tevatron is calculated within the nonrelativistic QCD factorization framework. The contribution from radiative decays of P-waveExpand
Measurement of the inclusive J/$$\psi $$ψ polarization at forward rapidity in pp collisions at $$\mathbf {\sqrt{s} = 8}$$s=8 TeV

Gluon Contribution to Hadronic J/psi Production
Using the recent CERN and Fermilab measurements for $\frac{J}{\ensuremath{\psi}}$ production by ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$, ${K}^{\ifmmode\pm\else\textpm\fi{}}$, $p$, andExpand
Quarkonium polarization in heavy ion collisions as a possible signature of the quark gluon plasma
The polarization of quarkonium states produced in hadron collisions exhibits strong non-perturbative effects - for example, at small transverse momentum $p_t$ charmonia appear unpolarized, in sharpExpand
Hadronic production of the new resonances: Probing gluon distributions
Assuming that the new resonances observed at 3095 and 3684 MeV are bound states of a new, heavy quark and its antiquark, we consider several models for the production of such states in hadronicExpand
$J/\psi$ production in $p \bar{p}$ collisions at $\sqrt{s}$ = 1.8-TeV
We have studied J/ψ production in pp collisions at √s = 1.8 TeV with the D∅ detector at Fermilab using μ + μ - data. We have measured the inclusive J/ψ production cross section as a function of J/ψExpand
$J/\psi$ Suppression by Quark-Gluon Plasma Formation
If high energy heavy ion collisions lead to the formation of a hot quark-gluon plasma, then colour screening prevents ce binding in the deconfined interior of the interaction region. To study thisExpand
