Section D: Deconfinement

The LHC heavy-ion physics program aims at investigating the properties of strongly interacting matter in extreme conditions of temperature and energy density where the formation of the Quark Gluon Plasma (QGP) is expected. In high-energy heavy-ion collisions, heavy quarks and quarkonium states are regarded as efficient probes of the properties of the QGP as they are created on a short time...

173. Lattice NRQCD study on the in-medium modification of Bottomonium spectra using a novel Bayesian reconstruction

Section D: Deconfinement

We present the results of a recent study on the in-medium modification of the spectral properties of Bottomonium S-wave (\Upsilon) and P-wave (\chi_b1) states. The light degrees of freedom of the surrounding medium are represented by 48^3x12 HotQCD lattices with Nf=2+1 HISQ flavors, which span the temperature range 140.40(MeV)(= 0.911T_C) < T < 248.63(MeV)(= 1.614T_C). The heavy quarks on the...

68. Heavy-flavour dynamics in proton-proton and nucleus-nucleus collisions at LHC

Section D: Deconfinement

I will present recent results on heavy-quark quenching, elliptic flow and azimuthal correlations in proton-proton and nucleus-nucleus collisions at LHC energies. We simulate the c-cbar and b-bbar pair initial creation with a perturbative QCD approach (POWHEG+PYTHIA). Successively we study the propagation of the heavy quarks in the plasma with the relativistic Langevin equation, by using...

4. Heavy quarkonium suppression in a fireball

Section D: Deconfinement

The dissociation of heavy quarkonium seen in heavy-ion collisions is a phenomena that allows to extract information of the produced thermal medium. This was believed to be due to the screening of the static potential, but recently perturbative computations and some lattice studies have pointed out to the possibility of having an imaginary part of the potential that would also contribute to...
