Glauber quark and gluon contributions to quark energy loss at next-to-leading order and next-to-leading twist
Amit Kumar, Gojko Vujanovic
The higher-twist formalism is used at to compute all possible medium-induced single-scattering emission kernels for an incoming highly energetic and virtual quark trave…
Fluctuation-Dissipation Relation for Hard Partons in a Gluonic Plasma
Amit Kumar, Abhijit Majumder, Ismail Soudi +1
We derive a fluctuation dissipation relation connecting the drag and diffusion jet transport coefficients for an energetic light quark traversing a non-perturbative thermalized glu…
Bremsstrahlung photon contributions to parton energy loss at high virtuality () : a perturbative calculation at
Amit Kumar, Gojko Vujanovic
In this work, real photon production scattering kernels from jet-medium interactions in the QCD medium are perturbatively calculated using the higher-twist (HT) formalism. Focus is…
Interplay of prompt and non-prompt photons in photon-triggered jet observables
Chathuranga Sirimanna, Yasuki Tachibana, Abhijit Majumder +49
Prompt photons are important yet challenging to observe in relativistic heavy-ion collisions, as they are produced in the early stages and traverse almost the entire QGP medium wit…
Effects of hadronic reinteraction on jet fragmentation from small to large systems
Hendrik Roch, Aaron Angerami, Ritu Arora +49
We investigate the impact of the hadronic phase on jet quenching in nuclear collider experiments, an open question in heavy-ion physics. Previous studies in a simplified setup sugg…
Modified Coherence and the Transverse Extent of Jets
Amit Kumar, Abhijit Majumder, Chathuranga Sirimanna +1
We present a study of the transverse size of parton showers and their diminishing interaction with the medium in the high virtuality stage of jet evolution. We consider the process…
