Energy-Energy Correlators in $Z$ -Tagged Jets in $pp$ Collisions

João Barata, Zhong-Bo Kang, Xoán Mayo López +2

We present predictions for the collinear energy-energy correlator (EEC) measured inside $Z$ -tagged jets in proton-proton collisions across the confinement transition. Our framework…

Anomaly Realization in Charge-Flux Detector Correlators

João Barata, Ratmir Jumanov, Andrey V. Sadofyev

Quantum anomalies provide a bridge between ultraviolet properties of a theory and its infrared sector. We study how this connection appears in axial-charge-flow observables. In the…

Mapping jet substructure in heavy-ion collisions with track functions

João Barata, Yeonju Go, Daniel Pablos

We investigate the dynamics of high-energy QCD cascades in heavy-ion collisions, focusing on modifications to jets' substructure induced by the presence of a quark-gluon plasma (QG…

Quantum simulating multi-particle processes in high energy nuclear physics: dijet production and color (de)coherence

João Barata, Meijian Li, Wenyang Qian +2

Hard scattering events in high-energy collisions produce highly virtual partons that subsequently fragment into collimated hadronic cascades. When such partonic showers evolve in a…

Hydrodynamics and Energy Correlators

João Barata, Matvey V. Kuzmin, Ian Moult +2

We study energy-energy correlators (EECs) in many-body quantum states, focusing on the matter produced in the aftermath of heavy-ion collisions. We analyze the angular structure of…

Early-Time Dynamics of Heavy-Ion Collisions through Energy Correlators: celestial blocks and the spacetime structure of out-of-equilibrium QCD matter

João Barata, José Guilherme Milhano, Andrey V. Sadofyev +1

Ultrarelativistic heavy-ion collisions provide a unique window into far-from-equilibrium states of QCD matter. The initial stages of these events are characterized by highly anisot…

Directional dead-cone effect in QCD matter

João Barata, Matvey V. Kuzmin, Xoán Mayo López +2

We consider the propagation of heavy quarks through a dense, hydrodynamically flowing QCD medium, representative of the quark-gluon plasma formed in ultrarelativistic heavy-ion col…

Jet quenching in out-of-equilibrium QCD matter

João Barata, Kirill Boguslavski, Florian Lindenbauer +1

We present the first study of jet substructure modifications during the bottom-up evolution that describes the early stages of heavy-ion collisions. To this end, we study the brems…

Heavy Quark Pair Energy Correlators: From Profiling Partonic Splittings to Probing Heavy-Flavor Fragmentation

João Barata, Jasmine Brewer, Kyle Lee +1

We introduce heavy-flavor energy correlators, $⟨ Ψ∣ E_{H} (n_{1}) E_{H} (n_{2}) ∣Ψ ⟩$ , as a powerful observable for profiling…

Quark antenna in early stage anisotropic QCD matter

Joao Barata, Carlos A. Salgado, Joao M. Silva

The states of matter produced in the early stage of heavy ion collisions can be highly anisotropic. If such a feature is sufficiently pronounced, one should expect the final partic…

Dissecting Jet Modification in the QGP with Multi-Point Energy Correlators

João Barata, Ian Moult, Andrey V. Sadofyev +1

Energy correlators have recently attracted significant attention in the study of heavy ion collisions due to their potential to robustly connect experimental measurements with an u…

Giving wake to energy-energy correlators: Hydrodynamic response on the celestial sphere

João Barata, Matvey V. Kuzmin, José Guilherme Milhano +1

The observation of the medium response generated by the propagation of high energy partons in the quark gluon plasma produced in heavy-ion collisions would provide a clear and unmi…

Tracking Energy Loss in Heavy Ion Collisions

João Barata, Ian Moult, João M. Silva

The main modification to high $p_{t}$ jets evolving in the quark gluon plasma is the depletion of their energy to the thermal background. Despite the prominent role played by energy…

Gluon to $q q ˉ$ antenna in anisotropic QCD matter: spin-polarized and azimuthal jet observables

João Barata, Carlos A. Salgado, João M. Silva

We study the production of a quark-antiquark antenna in the presence of a dense and anisotropic QCD medium. We assume the antenna to originate from an unpolarized gluon state, and…

Jet quenching in the glasma phase: medium-induced radiation

João Barata, Sigtryggur Hauksson, Xoán Mayo López +1

Inspired by the recent considerations of parton momentum broadening in the glasma phase, we study the medium-induced soft gluon radiation of jet partons at early times in heavy-ion…
