Description

A workshop, starting from the research topics covered by Prof. Wanda Alberico during her career, to explore hot topics in nuclear many-body physics, focusing on the hot-dense matter produced in heavy-ion collisions and present in compact objects like neutron stars.

The workshop will take palce in aula Vallauri (Istituto Galileo Ferraris, C.so Massimo D'Azeglio 42), close to the Physics Department.

      Relativistic Heavy Ion Collisions and Nuclear Structure

      In this talk, I shall discuss unexpected connections that have emerged recently
      between nuclear structure and relativistic heavy ion collisions. In particular, I
      shall show how the flow patterns of particles produced in heavy ion collisions at
      high energy can provide accurate information on low energy properties of nuclei,
      such as deformations, collective modes, etc

      From relativistic ion collisions to nuclear structure and back

      In recent years an intriguing and somehow surprising connection between low-energy nuclear structure and high-energy ion collisions has been established.
      In this talk I will discuss such a connection by first reviewing some results of nuclear structure theory and then applying them to the description of hadron distributions in relativistic nuclear collisions.

      Constraints on the Neutron Star Matter Equation-of-State

      Observations of the heaviest neutron stars, together with mass and radius
      measurements, and gravitational wave signals from binary neutron neutron star
      mergers, progressively tighten the constraints on the equation-of-state of dense
      baryonic matter. Using the presently available data base, results are presented of
      detailed Bayesian inference analyses. A focus is on prerequisites and limitations
      for hypothetical phase transitions at the baryon densities realized in neutron star
      cores. The possible structure and composition of matter under such conditions are
      discussed.

      Extending the fluid dynamic description to times before the collision

      Over the past two decades, research has shown that various observables measured in heavy-ion collisions can be effectively described using relativistic fluid dynamics across different collision systems and energies. However, a common challenge in these studies is the modeling of the transition from the initial state to the fluid-dynamic phase. While the collision likely involves complex, far-from-equilibrium dynamics, it is possible that a second-order fluid theory can adequately capture its softer features. In our work (arXiv:2410.08169), we investigate this possibility. We discuss how to characterize the state prior to the collision within this framework, the implications of relativistic causality on the equations of motion, the entropy production from shear and bulk viscous dissipation during the initial longitudinal dynamics, and how this can inform sensible initial conditions for subsequent transverse expansion. If successfully completed, this approach could lead to a comprehensive dynamical description of a heavy-ion collision, where the only free parameters are related to the thermodynamics and the transport properties of quantum chromodynamics.
