ABSTRACT: Mesons composed of heavy quark-antiquark pairs, known as quarkonia, provide the only direct probe of the screening length in the deconfined state of quarks and gluons, known as the quark gluon plasma (QGP), which is believed to be ...

We have carried out a wide study of Cold Nuclear Matter (CNM) effects on J/[Psi] = production in dAu, CuCu and AuAu collisions at √s{sub NN} = 200 GeV.

We present a wide study on the comparison of different shadowing models and their influence on J/[psi] production. We have taken into account the possibility of different partonic processes for the c{bar c}-pair production.

We report on J/[psi] production from asymmetric Cu+Au heavy-ion collisions at \(\sqrt{s_{\mathrm{NN}}} = 200\) GeV at the Relativistic Heavy Ion Collider at both forward (Cu-going direction) and backward (Au-going direction) rapidities.

This thesis presents the first J/psi production analysis of Au+Au reactions at forward rapidity at [square root]sNN = 200 GeV.

Results are presented for d+Au collisions at √S{sub NN} = 200 GeV and for d+Pb collisions at √S{sub NN} = 6.2 TeV. To contrast the centrality dependence in pA and dA collisions, they also present pPb results at √S{sub NN} = 8.8 TeV.

The STAR collaboration at RHIC presents measurements of J/[psi] → e+e− at mid-rapidity and high transverse momentum (p{sub T} > 5 GeV/c) in p+p and central Cu+Cu collisions at √sNN = 200 GeV.

The level of 'anomalous' charmonium suppression in high-energy heavy-ion collisions and its interpretation as a signal of quark-gluon plasma formation requires a robust understanding of charmonium production and absorption in proton-nucleus ...
