Lattice-based equation of state with a critical point from constant entropy contours and its comparison to effective QCD approaches
Hitansh Shah, Mauricio Hippert, Jorge Noronha +2
In this work, we systematically assess the performance of a new method from [H. Shah et al., Phys. Rev. C 113, L012201] for locating the QCD critical point using constant-entropy c…
Searching for the QCD critical point through constant entropy density contours
Hitansh Shah, Mauricio Hippert, Jorge Noronha +2
We propose a novel method to locate the QCD critical point by constructing an expansion along contours of constant entropy density. Applying two independent analysis of lattice QCD…
Chiral symmetry breaking and pion condensation in the early universe
Osvaldo Ferreira, Eduardo S. Fraga, Maurício Hippert +1
We determine the possible trajectories the universe may have followed in the QCD phase diagram during the QCD epoch. We focus on the roles of chiral symmetry breaking and pion cond…
Locating the QCD critical point through contours of constant entropy density
Hitansh Shah, Mauricio Hippert, Jorge Noronha +2
We propose a new method to investigate the existence and location of the conjectured high-temperature critical point of strongly interacting matter via contours of constant entropy…
Surface tension of dense matter at the chiral phase transition
Eduardo S. Fraga, Maurício Hippert, Andreas Schmitt
If a first-order phase transition separates nuclear and quark matter at large baryon density, an interface between these two phases has a nonzero surface tension. We calculate this…
New class of compact stars: Pion stars
Bastian B. Brandt, Gergely Endrodi, Eduardo S. Fraga +3
We investigate the viability of a new type of compact star whose main constituent is a Bose-Einstein condensate of charged pions. Several different setups are considered, where a g…
Features of the QCD phase diagram from small, noisy, fluctuating systems
Eduardo S. Fraga, Maurício Hippert
Current heavy-ion collision experiments might lead to the discovery of a first-order chiral symmetry breaking phase-transition line, ending in a second-order critical point. Nevert…
Multiplicity fluctuations near the QCD critical point
Maurício Hippert, Eduardo S. Fraga
Statistical moments of particle multiplicities in heavy-ion collision experiments are an important probe in the exploration of the phase diagram of strongly interacting matter and,…
Critical versus spurious fluctuations in the search for the QCD critical point
Maurício Hippert, Eduardo S. Fraga, Edivaldo M. Santos
The neighborhood of the QCD chiral critical point is characterized by intense fluctuations of the chiral field which could, in principle, generate pronounced experimental signature…
