LHC jet suppression of light and heavy flavor observables
Jet suppression of light and heavy flavor observables is considered to be an
excellent tool to study the properties of QCD matter created in
ultra-relativistic heavy ion collisions. We calculate the suppression patterns
of light hadrons, D mesons, non-photonic single electrons and non-prompt
in Pb+Pb collisions at LHC. We use a theoretical formalism that takes
into account finite size {\it dynamical} QCD medium with finite magnetic mass
effects and running coupling, which is integrated into a numerical procedure
that uses no free parameters in model testing. We obtain a good agreement with
the experimental results across different experiments/particle species. Our
results show that the developed theoretical formalism can robustly explain
suppression data in ultra relativistic heavy ion collisions, which strongly
suggests that pQCD in Quark-Gluon Plasma is able to provide a reasonable
description of the underlying jet physics at LHC.Comment: 4 pages, 2 figure
RHIC and LHC jet suppression in non-central collisions
Understanding properties of QCD matter created in ultra-relativistic
heavy-ion collisions is a major goal of RHIC and LHC experiments. An excellent
tool to study these properties is jet suppression of light and heavy flavor
observables. Utilizing this tool requires accurate suppression predictions for
different experiments, probes and experimental conditions, and their unbiased
comparison with experimental data. With this goal, we here extend our dynamical
energy loss formalism towards generating predictions for non-central
collisions; the formalism takes into account both radiative and collisional
energy loss, dynamical (as opposed to static) scattering centers, finite
magnetic mass, running coupling and uses no free parameters in comparison with
experimental data. Specifically, we here generate predictions for all available
centrality ranges, for both LHC and RHIC experiments, and for four different
probes (charged hadrons, neutral pions, D mesons and non-prompt ). We
obtain a very good agreement with all available non-central data, and also
generate predictions for suppression measurements that will soon become
available. Finally, we discuss implications of the obtained good agreement with
experimental data with different medium models that are currently considered.Comment: 6 pages, 4 figure
