Charlotte Van Hulse (Vrije Universiteit Brussel (VUB))10/26/26, 9:10 AM
The study of hard exclusive processes in lepton-hadron and hadron-hadron collisions provides, through its sensitivity to generalised parton distributions (GPDs), information on multi-dimensional quark and gluon distributions and on the distribution of internal forces inside nucleons and nuclei. After an introduction to these concepts, existing and planned measurements will be presented and...

A central goal of the future Electron-Ion Collider and of upcoming upgrades at the Large Hadron Collider is the search for a new regime of nuclear matter known as the Color Glass Condensate (CGC). In this extreme state, matter is dominated by an exceptionally dense population of gluons, the particles responsible for binding quarks inside protons and nuclei. Over the past two decades,...

We have developed a new numerical model to tackle an important problem of heavy-ion physics: the missing link between the pre-equilibrium Glasma and the resulting quark gluon plasma (QGP) stage. Our model simulates the nonperturbative production and real-time dynamics of the quarks from the Glasma. In this presentation, we will introduce our model and report on the role of particle production...

Chiral effective field theory (chiral EFT) provides a systematic framework for understanding the long-range forces between hadrons based on QCD. Recent advances in femtoscopic measurements [1] have expanded experimental access to hadron–hadron interactions beyond the nucleon–nucleon system, while lattice QCD has provided quantitative results for heavy-quarkonium–nucleon interactions at a...

Much of the physics in the cold-dense region in the QCD phase diagrams are characterised by the formation of Cooper pairs on the Fermi surface. In two-flavour symmetric quark matter, a phase transition is expected to occur into the two-flavour colour superconducting (2SC) phase. A key feature of this phase is that certain quarks remain ungapped due to repulsive colour-symmetric interactions....

Heavy quarks propagating through quark-gluon plasma provide a unique, experimentally accessible, opportunity to study the real-time dynamics of QCD in its strongly coupled regime. In the infinite heavy quark mass limit, the momentum change probability of a heavy quark in a thermal environment is characterized by the thermal expectation value of a Wilson loop featuring two long antiparallel...

I present recent developments in the HAL QCD method on hadron interactions in lattice QCD. Topics cover optimized two-baryon operators, Hermiticity and non-Hermiticity in HAL QCD potentials, dibaryons, exotic hadrons such as $T_{cc}$ and $T_{bb}$, and experimental confirmation of hadron interaction extracted in the HAL QCD method by Femtoscopy.

The properties of hyperon in nuclear matter provides an important link toward extending our understandings of neutron stars and QCD matter. We present our investigations of hyperon single-particle potentials in nuclear matter. Our recent efforts to construct a microscopic effective theory for QCD at finite density will also be presented.

87. What can we learn about the cold matter equation of state of QCD while evading the sign problem?Thomas Cohen (University of Maryland)10/27/26, 9:00 AM(3rd week, Oct. 26-30) Symposium
The equation of state of cold matter in QCD is a central issue in particle physics, nuclear physics as well as the astrophysics of neutron stars. Unfortunately, direct lattice calculation of the equation of state as a function of density using lattice methods are not viable due to an exponentially bad sign problem when a chemical potential is included. However, this need not mean that...

We study the phase structure of hot, dense QCD matter within five-dimensional anisotropic holographic models of Einstein–dilaton–Maxwell type, which support both primary and magnetic-field-induced anisotropies. The background equations are solved in fully analytic form for the light- and heavy-quark cases, allowing us to locate the first-order and crossover phase transitions and to construct...

Michele Pepe (INFN - sezione Milano Bicocca)10/27/26, 10:45 AM
Understanding QCD at high temperatures is essential for describing strongly interacting matter and the evolution of the early Universe. I will present a non-perturbative determination of the Equation of State of QCD with three massless quark flavours, covering temperatures from 3 GeV up to the electroweak scale and smoothly connecting to the low-temperature regime. The comparison with...

It is well known that superfluid phonons, which are Nambu-Goldstone modes resulting from the spontaneous breaking of $U(1)$ symmetry, can be described in terms of a dual two-form gauge field. In this two-form language, quantized vortex lines are formulated as degrees of freedom carrying dual charges.

Self-bound quantum droplets appear in various physical contexts, ranging from cold atomic gases to QCD matter such as those found in neutron stars. In this presentation, we discuss a universal effective field theory that describes the low-energy dynamics of small-amplitude surface oscillations in such diverse quantum droplets, independent of their microscopic binding mechanisms [1].

The QCD-CP of a second-order naturecomes to exist when an explicit chiral symmetry breaking is present at finite baryon density where the charge-conjugation symmetry is lost. Thus, the order parameter of it is a linear combination of the baryon density and... -
Noriyuki Sogabe (University of Osaka)10/27/26, 4:25 PM(3rd week, Oct. 26-30) Symposium
We show that Landau quantization in strongly magnetized two-flavor color-superconducting quark matter suppresses the conventional Fermi-surface contribution to the transverse Meissner response, allowing it to be controlled by the quantum geometry of the quasiparticle states. As a result, the transverse Meissner mass scales with the pairing gap, in contrast to the conventional chemical...

Michał Marczenko (Hiroshima University)10/27/26, 4:55 PM
In this talk, I present our recent results on the hadron spectra in QCD. We show that hadrons in QCD follow a spectrum determined by string dynamics characterized by a universal Hagedorn temperature linked to the string tension. This behavior was recently established for light hadrons and glueballs [1, 2]. We also demonstrate that the same dynamics describes the heavy-flavor sector [3]. The...

Heavy-ion collision experiments have provided compelling evidence that quarks and gluons can behave as a strongly interacting, low-viscosity relativistic liquid over distance scales not much larger than the size of a proton. Meanwhile, gravitational-wave observations of binary neutron star mergers have made understanding the dynamics of extremely dense matter in strong gravitational fields...

Quantum metric, which defines a distance on Hilbert space, has become an important notion in describing many-body physics. While quantum-metric effects in electric currents have been actively discussed in condensed matter physics, the fundamental aspects of kinetic theory incorporating quantum metric remain largely unexplored. In this talk, I will show general features of such a kinetic...

In recent years the phase diagram of the QGP, produced in HIC, was investigated for light quarks (u, d, s) and heavy quarks (c, b) separately, and different types of the phase transition pictures in these pure cases were brought out. The realistic model construction requires to take into account, that light and heavy quarks should be present in the HIC products together. This problem raises a...

The QCD phase structure at finite temperature and density remains largely unexplored because of the sign problem. At purely imaginary chemical potential, however, lattice QCD simulations can be performed without this difficulty. In particular, at $\mu_q/T=i\pi/3$, the Roberge--Weiss (RW) transition occurs as a consequence of the $Z_3$ symmetry. The nature of the RW endpoint depends on the...

Sejal Singh (Sophia University, BITS Pilani)10/28/26, 3:05 PM(2nd week, Oct. 19-23) QCD Matter under Extreme Conditions
In non-central heavy-ion collisions, the colliding nuclei carry a large amount of angular momentum, which can be transferred to the hot and dense partonic medium known as quark-gluon plasma (QGP) created in the interaction region. This gives rise to a vortical structure of the medium which is subsequently reflected in the polarization of final-state hadrons. Several theoretical frameworks have...

Finite-size effects modify the QCD phase diagram not only at real but also at complex values of the thermodynamic parameters. In this talk, we discuss these effects in an effective model framework that can describe finite-size scaling and the Lee-Yang zeros in finite volumes, while exhibiting a critical point in the thermodynamic limit. We compare several methods for locating the criticality...

The order of the chiral phase transition in the plane of temperature, $T$, and chemical potential, $\mu$, continues to puzzle. I conjecture that for massless quarks, the chiral phase transition at $(T_\chi,\mu_\chi)$ is syncretic: terms which break the axial $U(1)_A$ symmetry are fractional powers of 't Hooft determinants in the broken phase (for $N_c$ colors, an integer times $1/N_c$) but...

I will argue that if black holes represent one the most fascinating implications of Einstein's theory of gravity, neutron stars in binary system are its richest laboratory, where gravity blends with astrophysics and particle physics. I will discuss the rapid recent progress made in modelling these systems and show how the gravitational signal can provide tight constraints on the equation of...

As our understanding of cold, extremely dense matter grows, a multidisciplinary approach that combines recent progress in multimessenger neutron-star observations with theoretical knowledge of the equation of state (EoS) becomes increasingly essential.

Hadronic stars and strange quark stars could coexist within the so-called two-families scenario. In this respect, hadronic matter and strange quark matter correspond to two distinct equilibrium phases described by two different equations of state. I will present the first detailed Bayesian analysis that makes use of astrophysical and laboratory data in order to constrain the equations of state...

Neutron stars provide a unique astrophysical laboratory for probing dark matter under extreme density and strong gravity.

The baryon mass originates from spontaneous chiral symmetry breaking and a chiral invariant mass. The chiral invariant mass of hyperons has not been sufficiently considered. In this study, we investigate the dependence of the density at which hyperons appear on their chiral invariant masses in neutron star matter. We employ SU(2)_L x SU(2)_R chiral symmetry and introduce the chiral invariant...

QCD with massless quarks has a temperature-driven chiral phase transition. Contrary to historical analytic and numerical expectations, recent lattice simulations find no evidence for a first-order chiral transition for any number of massless flavors N_f studied. It is therefore natural to ask whether the transition might be second order for all N_f. I will explain the constraints on this...

We present a formulation for understanding color confinement on the basis of quantum reference frames (QRFs) and relational observables. In the QRF approach to color confinement, colored quantities are not defined as isolated local fields, but rather as relational observables with respect to a color frame or a dressing field. By the Gauss law, local color charge is excluded from the physical...

It has been demonstrated that the Quantum Yang Baxter Equations (QYBE) govern the dynamics of the Nambu-Goldstone bosons due to the natural constraints coming from the relations. In such a case, the problem of connecting dispersion relations with the number of Nambu-Goldstone bosons is solved naturally. The QYBE were also employed for finding constraints on the neutrino oscillation matrices,...
