“…Measurements of the D yield in jets probe the production processes in which the observed D mesons are formed primarily from gluon splitting into c ¯ c or b¯b pairs. The charm content in jets is calculable in perturbative QCD, and the leading non-perturbative correction is expected to be significant at LHC energies. …”

“…ALICE (A Large Ion Collider Experiment) is a general purpose heavy-ion detector at the CERN LHC addressing the physics of strongly interacting matter and the quark-gluon plasma in nucleus-nucleus collisions. ALICE has been recording physics data since the first proton-proton collisions at LHC as reference for the heavy-ion programme and to address physics topics for which it is complementary to the other LHC detectors. …”

“…The boson + jet probe, composed of a color neutral boson and color sensitive jet, has been called the `golden channel' for understanding the interactions of color sensitive objects in the quark gluon plasma. This analysis presents a study of azimuthally correlated $Z$ boson + jet events observed in the 2011 LHC Pb+Pb run at $\sqrt{s_{NN}}=2.76$ TeV using the ATLAS detector. …”

“…--HTML-->Heavy quarkonium states are considered as one of the key observables for the study of the phase transition from a system made of hadrons towards a Quark-Gluon Plasma. In the last 25 years, experiments at CERN and Brookhaven have studied collisions of heavy ions looking for a suppression of charmonia/bottomonia, considered as a signature of the phase transition. …”

“…In the first case, the measurements of DIS and SIDIS asymmetries, including also high-$p_{T}$ hadron production and $D^{0}$ mesons, allow to access the nucleon longitudinal PDFs, their first moments and the gluon polarization. The LO analysis, performed by COMPASS have shown that $\Delta g/g$ is small around $x_{g}\simeq 0.1$, and its first moment should not be larger than 0.2 $−$ 0.3 in absolute value. …”

Measurements of the isolated-photon plus jet differential cross sections are presented as functions of the photon transverse energy, the jet transverse momentum, the jet rapidity, the difference in azimuthal angle between the photon and the jet, the photon-jet invariant mass and the scattering angle in the photon-jet centre-of-mass frame. …”

Because the electroweak bosons do not interact strongly in the plasma, measurements of their production rates can be predicted using standard high-energy event generators. …”
