Heavy quark state production in Pb-Pb collisions at =5.02 TeV
We estimate differential rapidity cross sections for , ,
, , and production via Pb-Pb
collisions at proton-proton energy =5.02 TeV. For the
, states we use the mixed heavy quark hyrid theory,
with these states being approximately 50\% standard and 50\% hybrid charmonium,
bottomonium meson states. This is an extension of previous work on heavy quark
state production via Cu-Cu and Au-Au collisions at =200 GeV.Comment: 7 pages, 4 figures. arXiv admin note: substantial text overlap with

Quarkonia production at forward rapidity in Pb+Pb collisions at TeV with the ALICE detector
The study of formation of heavy quarkonia in relativistic heavy ion
collisions provides important insight into the properties of the produced high
density QCD medium. Lattice QCD studies show sequential suppression of
quarkonia states with increasing temperature; which affirms that a full
spectroscopy, can provide us a thermometer for the matter produced under
extreme conditions in relativistic heavy ion collisions and one of the most
direct probes of de-confinement. Muons from the decay of charmonium resonances
are detected in ALICE Experiment in p+p and Pb+Pb collisions with a muon
spectrometer, covering the forward rapidity region(). The analysis of
the inclusive J/ production in the first Pb+Pb data collected in the fall
2010 at a center of mass energy of TeV is discussed.
Preliminary results on the nuclear modification factor () and the
central to peripheral nuclear modification factor () are presented.Comment: 2 figures. Proceedings for XXV International Symposium on Lepton
