Suppression of quarkonia production in high energy nuclear collisions relative to proton-proton collisions, due to the Debye screening of the quark-antiquark potential, was proposed as a signature of the formation of the Quark-Gluon Plasma (QGP). Measurement of production of various quarkonia states can provide insight into thermodynamic properties of the QGP since different states have...

Using the QCD sum rule with its operator product expansion reliably estimated from lattice calculations for the pressure and energy density of hot QCD matter, we calculate the strength of the $J/\psi$ wave function at origin and find that it decreases with temperature when the temperature is above the transition temperature. This result is shown to follow exactly that obtained from the...

Recently, we have proposed a microscopic approach for the quenching and thermalisation of heavy quarks (HQ) in URHIC [1-4], assuming that they interact with light partons through both elastic and radiative processes evaluated by resorting to some parameterization of the running coupling constant, while those partons are spatially distributed along hydrodynamical evolution of the hot medium....

107. Jet suppression at LHC: theory vs. experiment

Suppression of light and heavy flavor observables is one of the most important probes in studying the properties of QCD matter created at RHIC and LHC experiments. We will here provide the most up-to-date light and heavy flavor suppression predictions for the available (2.76TeV) and the upcoming (~5TeV) Pb+Pb collisions at LHC. The predictions are based on our recent improvements in the energy...

110. Semi-classical approach to J/psi suppression in high energy heavy-ion collisions

Quarkonia suppression in heavy ion collisions has been investigated as a probe to Quark-Gluon Plasma properties and was indeed observed at SPS. However, the saturation of the suppression observed at RHIC and then is decrease at LHC has triggered the interest of our community and leads to consider alternate schemes as those based on sequential suppression in a stationary medium. In our...

79. Studies of Onia and Strangeness Production in Proton-proton Collisions at LHCb

Studies of strangeness and quarkonia production in the forward region provide important input to the understanding of QCD models in a kinematical range where they have large uncertainties. The LHCb experiment has collected a dataset corresponding to an integrated luminosity of about 3 fb-1 in proton-proton collisions at sqrt(s)= 7 and 8 TeV, as well as smaller samples recorded with other LHC...
