Jets in the vacuum and in the medium
Experimental
$\pi^{0}$ and $\eta$ mesons are probes for studying, among other interesting phenomena, the energy loss of partons traversing the hot and dense medium, the Quark-Gluon Plasma, that is formed in heavy-ions collisions. In addition, the study of $\pi^{0}$ and $\eta$ mesons in Pb-Pb collisions is necessary for the direct-photon measurement since these mesons constitute its most important...

Jets in the vacuum and in the medium
Experimental
Cu+Au collisions at RHIC generate asymmetric initial geometries and densities in both azimuth and rapidity. High $p_T$ $\pi^0$s produced in $\sqrt{s_{NN}}$ = 200 GeV Cu+Au collisions provide new environments to study parton energy loss in the Quark Gluon Plasma. including very central events where the Cu nucleus is enveloped by the Au nucleus. By measuring $\pi^0$ yields in $\phi$ relative...

Jets in the vacuum and in the medium
Experimental
One of the signatures of the strongly interacting medium produced in heavy ion collisions is the suppression of high-transverse momentum ($p_{\rm T}$) jets or so called ‘quenched jets’. In this talk, we present detailed measurements of nuclear modification factors and energy flow of quenched jets with the CMS detector. Those new results extend previous measurements to large angle with respect...

Jets in the vacuum and in the medium
Theory
The modifications of jets created in heavy-ion collisions at LHC energies enables us to study microscopic features of the quark-gluon plasma. The inherent hierarchy of scales governing the jet evolution allows to distinguish a leading jet structure, which interacts coherently with the medium as a single color charge, from softer sub-structures, which will be sensitive to effects of color...

Jets in the vacuum and in the medium
Theory
D mesons are considered to be excellent probes of QCD matter created in ultra relativistic heavy ion collisions. Here we examine charm quark suppression in central Au+Au collisions at RHIC, since D mesons have an advantage that fragmentation does not modify bare charm quark suppression. For this, we use a theoretical formalism based on energy loss calculations in a finite size dynamical QCD...

Jets in the vacuum and in the medium
Theory
Jet quenching has been proposed as a probe of QGP for more than a decade. It is still not clear how does jet loss its energy and how is the lost energy redistributed in the medium. In this talk, medium modification of γ-tagged jets and dijets in high-energy heavy-ion collisions is investigated within a Linearized Boltzmann Transport model for jet propagation that includes both elastic parton...
