We address the evolution of heavy-quarkonium states in an expanding quark-gluon plasma by
implementing effective field theory techniques in the framework of open quantum systems. In this
setting we compute the nuclear modification factors for quarkonia that are S-wave Coulombic bound states
in a strongly coupled quark-gluon plasma. The calculation is performed at an accuracy that is leading order
in the heavy-quark density expansion and next-to-leading order in the multipole expansion. The
quarkonium density-matrix evolution equations can be written in the Lindblad form, and, hence, they
account for both dissociation and recombination. Thermal mass shifts, thermal widths and the Lindblad
equation itself depend on only two nonperturbative parameters: the heavy-quark momentum diffusion
coefficient and its dispersive counterpart. Finally, by numerically solving the Lindblad equation, we
provide results for the ϒð1SÞ and ϒð2SÞ suppression.

Scattering and gluon emission in a color field : a light-front Hamiltonian approach
Li, Meijian; Lappi, Tuomas; Zhao, Xingbo (American Physical Society (APS), 2021)We develop a numerical method to nonperturbatively study scattering and gluon emission of a quark from a colored target using a light-front Hamiltonian approach. The target is described as a classical color field, as in ... -
Heavy quarkonium suppression in a fireball
Brambilla, Nora; Escobedo Espinosa, Miguel; Soto, Joan; Vairo, Antonio (American Physical Society, 2018)We perform a comprehensive study of the time evolution of heavy-quarkonium states in an expanding hot QCD medium by implementing effective field theory techniques in the framework of open quantum systems. The formalism ... -
Centrality dependence of high-pT D meson suppression in Pb-Pb collisions at √sNN = 2.76 TeV
ALICE Collaboration (Springer Berlin Heidelberg, 2015)The nuclear modification factor, RAA, of the prompt charmed mesons D0 , D+ and D∗+, and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at a centre-of-mass energy √ sNN = 2.76 TeV in two ... -

Event-by-event fluctuations in a perturbative QCD + saturation + hydrodynamics model: Determining QCD matter shear viscosity in ultrarelativistic heavy-ion collisions
Niemi, Harri; Eskola, Kari; Paatelainen, Risto (American Physical Society, 2016)We introduce an event-by-event perturbative-QCD + saturation + hydro (“EKRT”) framework for ultrarelativistic heavy-ion collisions, where we compute the produced fluctuating QCD-matter energy densities from next-to-leading-order ...
