“…The new Monte-Carlo based simulations of jet quenching in medium such as Jewel [34], Q-Pythia [35] and YaJEM [36] and complementary analytic calculations [37,38,39] recently became available. A strong broadening of showers in transverse momentum with respect to the jet axis results in wider angular distributions due to quenching in these analytic calculations.…”

Full jet reconstruction has traditionally been thought to be difficult in heavy ion events due to large multiplicity backgrounds. The search for new physics in high luminosity p+p collisions at the LHC similarly requires the precise measurement of jets over large backgrounds caused by pile up; this has motivated the development of a new generation of jet reconstruction algorithms which are also applicable in the heavy ion environment. We review the latest results on jetmedium interactions as seen in A+A collisions at RHIC, focusing on the new techniques for full jet reconstruction.

Based on these approaches, Monte Carlo tools for analyzing jet observables are being developed [76][77][78][79][80][81][82][83] and many phenomenological studies of jets in medium have been confronted with LHC measurements of a variety of jet observables , including intrajet observables like those that we shall focus on [85,89,99,101,104,[106][107][108][109].…”

Within the context of a hybrid strong/weak coupling model of jet quenching, we study the modification of the angular distribution of the energy within jets in heavy ion collisions, as partons within jet showers lose energy and get kicked as they traverse the strongly coupled plasma produced in the collision. To describe the dynamics transverse to the jet axis, we add the effects of transverse momentum broadening into our hybrid construction, introducing a parameter K ≡q/T 3 that governs its magnitude. We show that, because of the quenching of the energy of partons within a jet, even when K = 0 the jets that survive with some specified energy in the final state are narrower than jets with that energy in proton-proton collisions. For this reason, many standard observables are rather insensitive to K. We propose a new differential jet shape ratio observable in which the effects of transverse momentum broadening are apparent. We also analyze the response of the medium to the passage of the jet through it, noting that the momentum

“…This paper reports on progress in this direction. The angular distribution that we determine may be a useful ingredient to be implemented in Monte Carlo event generators that are developed by several groups [5,6,7,8]. The present work builds on the probabilistic equation that describes the in-medium QCD cascade, and which was derived recently [9].…”

Angular distribution of medium-induced QCD cascades

We provide a complete description of the angular distribution of gluons in a medium-induced QCD cascade. We identify two components in the distribution, a soft component dominated by soft multiple scatterings, and a hard component dominated by a few hard scatterings. The typical angle that marks the boundary between these two components is determined analytically as a function of the energy of the observed gluon and the size of the medium. We construct the complete solution (beyond the diffusion approximation) in the regime where multiple branchings dominate the dynamics of the cascade in the form of a power series in the number of collisions with the medium particles. The coefficients of this expansions are related to the moments of the distribution in the diffusion approximation and are determined analytically. The angular distribution may be useful in phenomenological studies of jet shapes in heavy-ion collisions.
