Tree-level soft emission of a quark pair in association with a gluon [PDF]
Journal of High Energy Physics, 2023 We compute the tree-level current for the emission of a soft quark-antiquark pair in association with a gluon. This soft current is the last missing ingredient to understand the infrared singularities that can arise in next-to-next-to-next-to-leading ...

Memory effects on energy loss and diffusion of heavy quarks in the quark-gluon plasma [PDF]
Physical Review D, 2022 We study the dynamics of heavy quarks in a thermalized quark-gluon plasma with a time-correlated thermal noise, η . In this case it is said that η has memory.

The physics behind ML-based quark-gluon taggers [PDF]
SciPost PhysicsJet taggers provide an ideal testbed for applying explainability techniques to powerful ML tools. For theoretically and experimentally challenging quark-gluon tagging, we first identify the leading latent features that correlate strongly with physics ...

Long-Range Azimuthal Correlation, Entanglement, and Bell Inequality Violation by Spinning Gluons at the Large Hadron Collider [PDF]
ResearchWe apply the recently developed concept of the nucleon energy–energy correlator (NEEC) for the gluon sector to investigate the long-range azimuthal angular correlations in proton–proton collisions at the Large Hadron Collider. The spinning gluon in these

Many-body correlations for nuclear physics across scales: from nuclei to quark-gluon plasmas to hadron distributions [PDF]
European Physical Journal A, 2023 It is an experimental fact that multi-particle correlations in the final states of high-energy nucleus-nucleus collisions are sensitive to collective correlations of nucleons in the wave functions of the colliding nuclei.

Jet substructure observables for jet quenching in quark gluon plasma: A machine learning driven analysis [PDF]
SciPost Physics, 2023 We present a survey of a comprehensive set of jet substructure observables commonly used to study the modifications of jets resulting from interactions with the Quark Gluon Plasma in Heavy Ion Collisions.

Quantum correlation in quark–gluon medium [PDF]
Journal of the Korean Physical Society, 2021 We study the thermodynamics and quantum correlations of the string cloud geometry whose field theory dual is the quark–gluon medium. We found the novel universality of the entanglement entropy first law in the high quark density limit.

Soft gluon–quark–antiquark emission in QCD hard scattering [PDF]
The European Physical Journal C, 2022 We consider the radiation of a soft gluon ( g ) and a soft quark–antiquark ( $$q{{\bar{q}}}$$ q q ¯ ) pair in QCD hard scattering. In the soft limit the scattering amplitude has a singular behaviour that is factorized and controlled by a soft current ...

Sources of multiparticle correlations – a microscopic perspective [PDF]
EPJ Web of Conferences, 2020 Multiparticle correlations is a hallmark measurement characterizing the behaviour of the assumed Quark Gluon Plasma in heavy ion collisions. In these proceedings an alternative, microscopic approach is presented, based on interacting strings and ...
