The strongly intensive quantity $\Sigma$ is a new observable, introduced recently to the domain of heavy-ion physics. In superposition models which assume independent particle production from statistically identical sources, $\Sigma$ is insensitive to the number of sources and its fluctuations, contrary to the standard forward-backward correlation coefficient ($b_{\rm corr}$). Therefore, it...

NA61/SHINE is an experiment at the CERN Super Proton Synchrotron. The main goals of the experiment are the search for the critical point of strongly interacting matter and study the properties of the onset of deconfinement. In order to reach these goals, the two-dimensional scan in beam momentum (13A-150A GeV/c) and system size (p+p, Be+Be, Ar+Sc, Xe+La, Pb+Pb) was performed.

We present the most recent results from the FASTSUM collaboration for hadron properties at high temperature from anisotropic lattice QCD. This includes the temperature dependence of the light and charmed meson and baryon spectrum, as well as properties of heavy quarkonia. We also present the status of our next generation gauge ensembles.

One of the primary goals of heavy-ion physics is to understand the transport properties of the quark-gluon-plasma (QGP) which comprises the tiniest constituents, quarks and gluons, that prevailed in the first few microseconds after the Big Bang.

Collective phenomena have proved to be crucial probes to the transport properties of the quark-gluon plasma (QGP) created in ultrarelativistic heavy-ion collisions. One manifestation of these effects is the anisotropic azimuthal distribution of the particles produced in such collisions, which can be parametrized with two distinct degrees of freedom: the flow amplitudes v_n and the symmetry...

Chiara De Martin8/2/22, 2:30 PMD: DeconfinementParallel Talk
One of the key challenges of hadron physics today is understanding the origin of strangeness enhancement in high-energy hadronic collisions, i.e. the increase of (multi-)strange hadron yields relative to non-strange hadron yields with increasing charged-particle multiplicity. What remains unclear is the relative contribution to this phenomenon from hard and soft QCD processes and the role of...

We develop a new approach to the initial state of heavy-ion collisions by extending the weak field approximation of the Color Glass Condensate formalism beyond the boost invariant limit [1]. Our analytical calculation yields surprisingly simple results for the color fields and the field strength tensor of the Glasma produced in the collision. As an explicit check, we demonstrate quantitative...

As a consequence of the theoretical improvements and the wide range of accurate experimental measurements, our understanding of the collective phenomena in heavy-ion collisions has advanced significantly over the past years. The Global Bayesian analysis played a substantial role in this advancement. In this talk, we present a global Bayesian analysis to infer the transport properties of...

Comparing the complex structure of the models of the quark gluon plasma is a useful way to better discern the physics following a heavy ion collision, in particular in the vicinity of a phase transition. In this talk, I will focus on quasinormal modes and the collisions of poles in the complex plane, first by using the chiral phase transition as an illustrative example...

Local quantum field theory (QFT) provides a framework for establishing the non-perturbative constraints imposed on finite-temperature correlation functions. In this talk I will discuss how the locality of fields has significant implications for the spectral properties of finite-temperature QFTs, in particular that the peak-broadening effects experienced by particle states can be directly...

Over the last decades, the theoretical picture of how hadronic jets interact with nuclear matter has been extended to account for the medium’s finite longitudinal length and expansion. However, only recently a first-principle approach has been developed that allows to couple the jet evolution to the medium flow and anisotropic structure in the dilute limit. In this talk, we will show how to...

The medium that forms in a heavy-ion collision modifies the properties of jets traversing it. These modifications give substantial information about the nature of the medium and, therefore, they are one of the main focuses of the heavy-ion program at LHC. The influence of the medium into highly energetic partons depends on correlators of Wilson lines, which have been studied in perturbation...

The fast development of quantum technologies over the last decades has offered a glimpse to a future where the quantum properties of multi-particle systems might be fully understood. In the context of jet quenching, quantum computers might allow for a better understanding of medium induced jet modifications which are hard to extract using traditional approaches. In this talk, I will focus on...

Quarkonium production has long been identified as one of the golden signatures of deconfinement in heavy-ion collisions. Recently, the production of J/$\psi$ via (re)generation within the quark-gluon plasma (QGP) or at the phase boundary has been considered a key ingredient for the interpretation of quarkonium measurements in Pb$-$Pb collisions at the Large Hadron Collider (LHC). In addition,...

Quarks of heavy flavors are useful tool to study quark-gluon plasma created in heavy-ion collisions. Due to their high mass and early production time, heavy quarks experience the entire evolution of the system created in these collisions. Open heavy flavor meson measurements are sensitive to the energy loss in the QGP, while quarkonia are sensitive to the temperature of the QGP as they...

Electromagnetic radiation from the quark-gluon plasma (QGP) is an important observable to be carefully considered in heavy ion collision experiments. At leading order in the electromagnetic coupling and all orders in the strong coupling, the photon and dilepton emission rates can both be determined from the QCD vector channel spectral function. In this talk, I will provide a status update from...

The High Acceptance DiElectron Spectrometer (HADES) is a versatile detector with particular focus on dielectron measurements in pion, proton, deuteron and (heavy-) ion-induced reactions using proton or nuclei targets in the SIS-18 energy range (1-2 GeV/nucleon). Its excellent particle identification capabilities also allow for the investigation of hadronic observables.

We study the chiral condensate for 2+1 flavor QCD with physical quarks within a non-interacting Hadron Resonance Gas (HRG) model. By including the latest information on the mass variation of the hadrons with respect to the light quark mass, from lattice QCD and chiral perturbation theory, we show that it is possible to quite accurately account for the chiral crossover transition even within a...
