Event-by-event quantum fluctuations in the initial stages of ultrarelativistic nucleus–nucleus collisions have been theoretically predicted to influence observables constructed from final-state quantities, such as azimuthal two-particle momentum correlations. In several instances, these predictions have been indirectly confirmed through comparisons between experimental data and...

Evidences of vortical effects have been recently found by experiments in heavy ion collisions, instigating new insights into the phase diagram of quantum chromodynamics. Considering the effect of rotations, lattice QCD calculations shows that temperatures for deconfinement and chiral symmetry restoration should increase with the angular velocity, and the dominant effects are related to...

We have explored the influence of angular velocity on the shear and bulk viscosities of a rotating QCD medium. In the noncentral events of the relativistic heavy ion collisions, the resulting QCD medium acquires finite angular momentum, giving rise to a finite angular velocity. This rotational motion can notably alter various properties of the hot QCD medium, including the viscous...

We propose a novel observable of jet thermalization in high-energy nuclear collisions, based on correlating $\Lambda$ hyperon polarization with vortex dynamics. Using hybrid simulations, we show that the deposition of energy and momentum by quenched jets generates toroidal vorticity rings, a ubiquitous structure in fluid dynamics. These rings induce a corresponding toroidal pattern of...

We compute the photon yield and elliptic flow coefficient in relativistic heavy-ion collisions from gluon fusion and splitting processes induced by a magnetic field. The calculation accounts for the intense magnetic field and the high gluon occupation number at early times. The photon production induced by these process represents an excess contribution over calculations without...

30. Universal Scaled Spectra: Bayesian Constraints on QGP Transport from Heavy-Ion Collisions

We present the first comprehensive Bayesian calibration of a state-of-the-art hybrid heavy-ion collision model incorporating a novel observable: the scaled particle spectra of pions. This observable isolates the intrinsic spectral shape and reveals a remarkable degree of universality across centrality classes and collision systems. Leveraging the JETSCAPE framework, we construct...

26. Effects of implicit flavor quark and meson mixings

Fabio L. Braghin (UFG)

Two types of flavor mixing interactions are derived and discussed in this work. First, quark and meson mixing interactions emerge in one-loop effective action calculation due to flavor symmetry breaking (FSB). Second, in the absence of some mixing interactions, an implicit flavor mixing emerge due to the different representations in which quarks and mesons belong to. To show this, the NJL...

27. From Sudakov effects in Single and double inclusive hadron production in DIS at small x to CSS evolution of quark TMD at large x

Jamal Jalilian-Marian

We calculate next to leading corrections to inclusive dihadron and single hadron production in DIS at small x using the Color Glass Condensate (CGC) formalism. We show how Sudakov effects arise in both cases and how to include them in the CGC approach. We then consider the standard quark TMD and derive the CSS evolution equation for evolution of quark TMD.
