Long Range Plan: Dense matter theory for heavy-ion collisions and neutron stars
Alessandro Lovato, Travis Dore, Robert D. Pisarski +61
Since the release of the 2015 Long Range Plan in Nuclear Physics, major events have occurred that reshaped our understanding of quantum chromodynamics (QCD) and nuclear matter at l…
Chiral restoration of strange baryons
Eduardo S. Fraga, Rodrigo da Mata, Savvas Pitsinigkos +1
We review the results of a phenomenological model for cold and dense nuclear matter exhibiting a chiral phase transition. The idea is to model the quark-hadron phase transition und…
Strange quark matter from a baryonic approach
Eduardo S. Fraga, Rodrigo da Mata, Savvas Pitsinigkos +1
We construct a model for dense matter based on low-density nuclear matter properties that exhibits a chiral phase transition and that includes strangeness through hyperonic degrees…
Insights on the peak in the speed of sound of ultradense matter
Maurício Hippert, Eduardo S. Fraga, Jorge Noronha
In this work we investigate the minimal physical requirements needed for generating a speed of sound that surpasses its asymptotic conformal limit. It is shown that a peak in the s…
Dynamics of critical fluctuations: Theory -- phenomenology -- heavy-ion collisions
M. Bluhm, M. Nahrgang, A. Kalweit +27
This report summarizes the presentations and discussions during the Rapid Reaction Task Force "Dynamics of critical fluctuations: Theory -- phenomenology -- heavy-ion collisions",…
Interacting quark matter equation of state for compact stars
Eduardo S. Fraga, Aleksi Kurkela, Aleksi Vuorinen
Lattice QCD studies of the thermodynamics of the hot quark-gluon plasma (QGP) demonstrate the importance of accounting for the interactions of quarks and gluons, if one wants to in…
Chiral pions in a magnetic background
Giuseppe Colucci, Eduardo S. Fraga, Armen Sedrakian
We investigate the modification of the pion self-energy at finite temperature due to its interaction with a low-density, isospin-symmetric nuclear medium embedded in a constant mag…
Chiral transition in a finite system and possible use of finite size scaling in relativistic heavy ion collisions
L. F. Palhares, E. S. Fraga, T. Kodama
We investigate finite-size effects on the chiral phase diagram of strong interactions within the linear sigma model coupled to quarks. We estimate the modification of the pseudocri…
Hydrodynamical instabilities in an expanding quark gluon plasma
C. E. Aguiar, E. S. Fraga, T. Kodama
We study the mechanism responsible for the onset of instabilities in a chiral phase transition at nonzero temperature and baryon chemical potential. As a low-energy effective model…
Dilute Nuclear Matter in Chiral Perturbation Theory
E. S. Fraga, Y. Hatta, R. D. Pisarski +1
We use chiral perturbation theory to compute the effective nucleon propagator in an expansion about low density in the chiral limit. We neglect four-nucleon interactions and focus…
The Equation of State for Cold and Dense Strongly Interacting Matter
E. S. Fraga, Y. Hatta, R. D. Pisarski +1
We discuss recent results for the equation of state for cold and dense strongly interacting matter. We consider the extreme cases of very high densities, where weak-coupling approa…
New Class of Compact Stars at High Density
Eduardo S. Fraga, Robert D. Pisarski, Jurgen Schaffner-Bielich
We discuss the equation of state for cold, dense quark matter in perturbation theory, and how it might match onto that of hadronic matter. Certain choices of the renormalization sc…
Hydrodynamic Models for Heavy-Ion Collisions, and beyond
A. Dumitru, J. Brachmann, E. S. Fraga +5
A generic property of a first-order phase transition in equilibrium, and in the limit of large entropy per unit of conserved charge, is the smallness of the isentropic speed of sou…
