High momentum suppression of light and heavy flavor observables is considered to be an excellent probe of jet-medium interactions in QCD matter created at RHIC and LHC. 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 developed the dynamical...

We study the double inclusive emission of gluons off a hard parton
propagating in thin QCD plasma. Within the N=1 opacity approximation, we determine the induced emission pattern of two gluons which are soft compared to
the parton energy but hard compared to the medium scale. We assume a wide separation between the energies of those two gluons, but we allow arbitrary ordering of their...

PHENIX has measured the inclusive jet cross-section at midrapidity
in $p$$+$$p$ collisions at $\sqrt{s_{NN}}$=200 GeV. Jets were
reconstructed from charged particles and electromagnetic calorimeter
clusters using the anti-$k_T$ algorithm with $R=0.3$ and a
Gaussian filter reconstruction algorithm. These small radii jet
reconstructions are needed as baseline measurements for...

In this talk we report measurements by the STAR collaboration
of the semi-inclusive yield and azimuthal distribution of
reconstructed charged jets recoiling from a high p_{T} hadron
trigger, in central and peripheral Au+Au collisions at \sqrt{s_{NN}} = 200 GeV. Corrections
for the large underlying background to jet observables in
heavy-ion collisions are carried out on an...

The ALICE experiment at the LHC performs measurements of neutral meson and direct photon inclusive spectra at mid-rapidity in a wide $p_{\rm T}$ range in $pp$, $p$-Pb and Pb-Pb collisions. Photons and neutral mesons ($\pi^{0}$, $\eta$, $\omega$) are reconstructed via complementary methods, using the ALICE electromagnetic calorimeters, PHOS and EMCal, and by the central tracking system,...

In relativistic heavy ion collisions, a hot medium with a high density of unscreened color charges is produced. One manifestation of the energy loss of jets propagating through the medium is a lower yield of jets emerging from the medium than
expected in the absence of medium effects. Therefore modifications of the jet yield are directly sensitive to the energy loss mechanism. Furthermore,...

The phenomenon of events containing highly asymmetric dijet pairs is one of the most striking results in heavy ion physics. It has provided the first direct observation of in-medium jet energy loss at the LHC. Detailed measurements of centrality-dependent dijet imbalance in $\sqrt{s_{NN}}=2.76$ TeV PbPb collisions using data collected in the 2011 LHC heavy ion run are presented. The new...
