Scheme Transformations in Non-Linear QCD Evolution: Towards a Stable NLO BK Equation
Renaud Boussarie, Paul Caucal, Piotr Korcyl +1
High-energy QCD evolution at NLO suffers from large collinear logarithms that make the perturbative expansion of the Balitsky-Kovchegov (BK) equation unstable. We develop a systema…
Energy-energy correlators and color decoherence from a generating functional
Yacine Mehtar-Tani
Using jet calculus at leading-logarithmic accuracy, we develop a generating-functional approach to describe the hard-collinear sector of jets propagating through the quark-gluon pl…

Hannah Bossi, Maxence Larose, Yacine Mehtar-Tani
We combine inclusive jet nuclear modification factors with energy-energy correlators to perform a data-driven extraction of the quark and gluon quenching factors and the medium res…
Color Coherence and the Soft Structure of QCD Jets in Vacuum and the QGP
Paul Caucal, Yacine Mehtar-Tani
We formulate a theoretical framework for the evolution of QCD jets in vacuum and in the quark--gluon plasma through the resummation of large energy logarithms. Exploiting the stron…

Paul Caucal, Kevin Eisenberg, Yacine Mehtar-Tani
We present a theoretical framework for jet fragmentation in heavy-ion collisions based on the resummation of large energy logarithms. Exploiting the hierarchy of scales characteris…
Rotating the Color Glass Condensate
Renaud Boussarie, Paul Caucal, Piotr Korcyl +1
High-energy QCD evolution beyond leading order suffers from instabilities driven by large collinear logarithms. We present a framework, consistent with the standard high-energy ope…
The Physics of Jet Quenching in Perturbative QCD
Yacine Mehtar-Tani
Hard processes in collider experiments typically produce QCD jets, which have long served as precision tests of QCD in the vacuum. More recently, heavy-ion programs at RHIC and the…
Collinear Structure of Nonlinear Small- Evolution
Renaud Boussarie, Paul Caucal, Yacine Mehtar-Tani
We introduce a novel approach to high-energy QCD factorization of cross-sections for processes involving a dilute projectile and a dense target. Our method preserves the factorizat…
Nonlinear dynamics of jet quenching
Yacine Mehtar-Tani
We present an analytic framework for jet quenching in dense QCD matter that unifies medium-induced branching with vacuum collinear evolution. Energy transported outside the jet reg…
Nuclear Cold QCD: Review and Future Strategy
F. Arleo, P. Caucal, A. Deshpande +12
This review examines data from hadron-nucleus collisions, primarily focusing on hard processes like Drell-Yan, heavy flavor and quarkonium production. It highlights observed modifi…
Open quantum system approach to inclusive jet production in heavy-ion collisions
Yacine Mehtar-Tani, Felix Ringer, Balbeer Singh +1
We derive a factorization formula for inclusive jet production in heavy-ion collisions using the tools of Effective Field Theory (EFT). We show how physics at widely separated scal…
Non-linear dynamics of jet quenching
Yacine Mehtar-Tani
We develop a comprehensive analytic framework for jet quenching in QCD media, based on a medium-induced parton cascade sourced by collinear virtual splittings. We show that the ene…
Factorization for jet production in heavy-ion collisions
Yacine Mehtar-Tani, Felix Ringer, Balbeer Singh +1
We develop an Effective Field Theory approach for jet observables in heavy-ion collisions, where the jet is treated as an open quantum system interacting with a hot and dense QCD m…
Jet Suppression and Azimuthal Anisotropy from RHIC to LHC
Yacine Mehtar-Tani, Daniel Pablos, Konrad Tywoniuk
Azimuthal anisotropies of high- particles produced in heavy-ion collisions are understood as an effect of a geometrical selection bias. Particles oriented in the direction in…

We revisit the high energy semi-classical description of the exclusive processes DVCS, TCS, and Double DVCS by explicitly keeping track of the Feynman dependence in both the ha…
Jet suppression and azimuthal anisotropy at RHIC and LHC
Yacine Mehtar-Tani, Daniel Pablos, Konrad Tywoniuk
Jets are multi-partonic systems that develop before interactions with the quark-gluon plasma set in and lead to energy loss and modifications of their substructure. Jet modificatio…
