Parallel Session 1.4: Jets and High pT Hadrons (I)
- David Morrison (BNL)
Direct photons, being colorless objects, provide an unmodified control particle that can be used in conjunction with jets to probe the quark-gluon plasma. To leading order the direct photon momentum balances the momentum of opposing jets and can therefore provide a clean handle on the jet energy. Therefore, angular correlations with direct photons provide a mechanism to study the fragmentation...
Jets and their modifications due to partonic energy loss provide a powerful tool to study the properties of the QGP created in ultrarelativistic heavy ion collisions. For correlation studies of jet energy loss, two complementary trigger object choices offer access to the initial hard parton’s energy: On the one hand, direct-photon–tagged jets are a self-generated tomographic medium probe,...
Jet-hadron correlations are used to extend measurements of the properties of jets beyond classic fixed-R jet reconstruction. New measurements using PbPb and pp collision data at $\sqrt{s_{NN}}$ = 5.02 TeV recorded by CMS use a statistical approach that allows for a reliable subtraction of the underlying event beyond the typical distance parameters of jet reconstruction. Measurements of...
We use a Linear Boltzmann Transport model (LBT model) coupled to (3+1)D ideal hydrodynamic evolution in real time with fluctuating initial conditions to simulate both the transport of jet shower partons and jet-induced medium excitation. In this coupled approach, soft partons from medium recoil and induced radiation from propagation of energetic shower partons in the Linear Boltzmann...
The final goal of the jet quenching studies is to extract medium parameters that characterize the QGP formed in high-energy nuclear collisions. In our analysis, we combine event-by-event hydrodynamics, within the EKRT formulation, with jet quenching (ASW Quenching Weights) to obtain high-$p_T$ $R_{AA}$, $v_2$ and $v_3$ for charged particles at RHIC and LHC energies for different...
