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 $K\equiv \hat q/T^3$ that governs its magnitude.

The angular structure of jet quenching within a hybrid strong/weak coupling model
/ Casalderrey-Solana, Jorge (Oxford U., Theor. Phys.) ; Gulhan, Doga Can (CERN) ; Milhano, José Guilherme (LIP, Lisbon ; CERN) ; Pablos, Daniel (Barcelona U. ; ICC, Barcelona U.) ; Rajagopal, Krishna (MIT, Cambridge, CTP)
Building upon the hybrid strong/weak coupling model for jet quenching, we incorporate and study the effects of transverse momentum broadening and medium response of the plasma to jets on a variety of observables. For inclusive jet observables, we find little sensitivity to the strength of broadening. [...]

A Comprehensive Analysis of Jet Quenching via a Hybrid Strong/Weak Coupling Model for Jet-Medium Interactions
/ Casalderrey-Solana, Jorge (Barcelona U., ECM ; ICC, Barcelona U. ; Oxford U., Theor. Phys.) ; Gulhan, Doga Can (MIT, LNS) ; Milhano, José Guilherme (Lisbon, CENTRA ; CERN) ; Pablos, Daniel (Barcelona U., ECM ; ICC, Barcelona U.) ; Rajagopal, Krishna (MIT, LNS)
Within a hybrid strong/weak coupling model for jets in strongly coupled plasma, we explore jet modifications in ultra-relativistic heavy ion collisions. Our approach merges the perturbative dynamics of hard jet evolution with the strongly coupled dynamics which dominates the soft exchanges between the fast partons in the jet shower and the strongly coupled plasma itself.

Boson-Jet Correlations in a Hybrid Strong/Weak Coupling Model for Jet Quenching in Heavy Ion Collisions

We confront a hybrid strong/weak coupling model for jet quenching to data from LHC heavy ion collisions. The model combines the perturbative QCD physics at high momentum transfer and the strongly coupled dynamics of non- abelian gauge theories plasmas in a phenomenological way. [...]

Jet suppression from small to large radius
/ Pablos, Daniel (speaker) (University of Bergen)
The angular dependence of jet suppression encodes key information about the process of energy and momentum hydrodynamization, and for this reason can be used to greatly improve our understanding of fundamental aspects of the jet/QGP interaction. In this work we study jet suppression from small to very large radius, for low and very high energy jets at the LHC and RHIC [...]

A Hybrid Strong/Weak Coupling Approach to Jet Quenching

We propose and explore a new hybrid approach to jet quenching in a strongly coupled medium. The basis of this phenomenological approach is to treat physics processes at different energy scales differently. [...]

Towards a hybrid strong/weak coupling approach to jet quenching

We explore a novel hybrid model containing both strong and weak coupling physics for high energy jets traversing a deconfined medium. This model is based on supplementing a perturbative DGLAP shower with strongly coupled energy loss rate. [...]

Jet quenching within a hybrid strong/weak coupling approach
/ Casalderrey-Solana, J. (Barcelona U., ECM ; ICC, Barcelona U.) ; Gulhan, Doga Can (MIT, LNS) ; Milhano, Jose Guilherme (Lisbon, CENTRA ; Lisbon, IST ; CERN) ; Pablos, Daniel (Barcelona U., ECM ; ICC, Barcelona U.) ; Rajagopal, Krishna (MIT, LNS)
We propose a novel hybrid model for jet quenching, including both strong and weak coupling physics where each seems appropriate. Branching in the parton shower is assumed to be perturbative and described by DGLAP evolution, while interactions with the medium result in each parton in the shower losing energy as at strong coupling, as realized holographically.

The wake of jets from linearized hydrodynamics
/ Casalderrey Solana, Jorge (speaker) (University of Barcelona)
Recently, jet substructure observables have been widely used in the study of jets. Some observables are sensitive to the wide angle soft particles within the jet, for example, the Lund plane distribution with different jet radii and soft drop parameters. [...]

Predictions for Boson-Jet Observables and Fragmentation Function Ratios from a Hybrid Strong/Weak Coupling Model for Jet Quenching
/ Casalderrey-Solana, Jorge (Barcelona U., ECM ; ICC, Barcelona U.) ; Gulhan, Doga Can (MIT, Cambridge, Dept. Phys. ; MIT, LNS) ; Milhano, José Guilherme (CERN ; Lisbon, CENTRA ; Lisbon, IST) ; Pablos, Daniel (Barcelona U., ECM ; ICC, Barcelona U.) ; Rajagopal, Krishna (MIT, LNS ; MIT, Cambridge, CTP)
We have previously introduced a hybrid strong/weak coupling model for jet quenching in heavy ion collisions that describes the production and fragmentation of jets at weak coupling, using PYTHIA, and describes the rate at which each parton in the jet shower loses energy as it propagates through the strongly coupled plasma, dE/dx, using an expression computed holographically at strong coupling. The model has a single free parameter that we fit to a single experimental measurement. [...]
