High-pt particles produced in nucleus-nucleus collisions constitute a powerful tool to study the medium properties. The energy loss resulting from the propagation of these particles in the produced medium translates into a suppression of the high-pt yields. These effects are usually associated to medium-induced gluon radiation which, in turn, predicts a broadening of the jet-like signals. Both the energy loss and the jet broadening are expected to increase proportionally to the medium density. In the more realistic case of a dynamically expanding medium, the gluon radiation becomes anisotropic due to the presence of a preferred direction in the transverse plane with respect to the axis of propagation. This anisotropy translates into deformed jet-shapes which provide new posibilities to study these flows by high-pt measurements.

Charged-particle nuclear modification factors in PbPb and pPb collisions at √(s_N N) = 5.02 TeV (2017, background): “This indicates that the medium created at the higher collision energy is closer to the ideal limit, q̂ ' 2ε3/4 [41], where ε is the energy density of the QGP.”
Transverse momentum spectra and nuclear modification factors of charged particles in pp, p-Pb and Pb-Pb collisions at the LHC (2018, methodology): “This approach consists of fitting a K factor, defined as K ≡ q̂/2 3/4, that quantifies departure of this parameter from the perturbative estimate, q̂ideal ∼ 2 3/4 [63], where the local energy density is taken from a hydrodynamical model of the medium.”

The saturation scale appearing in (3.24) is closely related to the transport coeﬃcient qˆ given by (3.13), namely [28, 49] Q2 s(x,L) = ˆqL.

Interference effects in medium-induced gluon radiation (2011, background): “While this mechanism for jet quenching has been quite successful in describing the suppression of single particle spectra observed at RHIC (see, for example [20, 21]), it has been realized for long that the respective data refer to inclusive measurements which are quite limited in constraining the u”
