114. Anomalous kaon correlations measured in Pb-Pb collisions at the LHC as evidence for the melting and refreezing of the QCD vacuum

Joseph Kapusta (Minnesota University)

Invited Talk

Measurements of the dynamical correlations between neutral and charged kaons in central Pb-Pb collisions at √s_NN = 2.76 TeV by the ALICE Collaboration display anomalous behavior relative to conventional heavy-ion collision simulators. We consider other conventional statistical models, none of which can reproduce the magnitude and centrality dependence of the correlations. The data can be...

113. Machine learning for lattice field theory and back

Gert Aarts

26/07/2023, 09:45

Invited Talk

Recently, machine learning has become a popular tool to use in fundamental science, including lattice field theory. Here I will review on some recent ideas, including normalising flow, phase classification and quantum-field theoretical machine learning. The latter combines insights of lattice field theory and machine learning to provide a fresh perspective on (hopefully) both.

3. Bose condensation in dense QCD

Prof. Jens Oluf Andersen

27/07/2023, 08:30

Invited Talk

In this talk, I will discuss recent progress in our understanding of pion and kaon condensation in dense QCD. Using chiral perturbation theory at finite isospin and strangeness density, we map out the phase diagram. We also include electromagnetic interactions. The equation of state, speed of sound, chiral and pion condensates are calculated to next-to-leading order in the low-energy...

64. A novel technique to access the residual strong interaction among hadrons at the LHC

Raffaele Del Grande (Technische Universitaet Muenchen (DE))

Invited Talk

The ALICE collaboration has delivered in recent years unprecedented precision information on the residual strong interaction for several hadron pairs in the strange quark sector. These results have been obtained by analyzing the momentum correlation of particle pairs produced in pp and p-Pb collisions at the LHC. In such colliding systems hadrons are emitted at relative distances of the order...

119. Recent progress in lattice QCD at non-zero temperature and density

Peter Petreczky

28/07/2023, 09:00

Invited Talk

I will review the progress in lattice QCD at non-zero temperature and
density, including the calculations
of the equation of state at non-zero baryon density, the nature of the
chiral transition as function of
the quark mass and quantitates related to heavy flavor probes of hot
matter. The latter includes, the
lattice calculation of the heavy quark diffusion constant, heavy...

112. A short walk through the physics of neutron stars

Isaac Vidana (INFN Catania)

Invited Talk

In this talk I will shortly review several aspects of the physics of neutron stars. After an introduction Particularly, I will review few aspects of their observation discussing, namely, the different types of telescopes that are used in their observation, the many astrophysical manifestations of these objects, and several observables such as masses, radii or gravitational waves. Finally, I...
