Journal ArticleDOI
QCD phenomenology based on a chiral effective Lagrangian
Tetsuo Hatsuda,Teiji Kunihiro +1 more
TL;DR: The Nambu-Jona-Lasinio (NJL) model as mentioned in this paper is a low-energy effective theory of QCD, and it has been applied to the system at finite temperature (T ) and density (ϱ) relevant to the early universe, interior of the neutron stars and the ultrarelativistic heavy ion collisions.
Journal ArticleDOI
The phase diagram of dense QCD
Kenji Fukushima,Tetsuo Hatsuda +1 more
TL;DR: The current status of theoretical studies on the quantum chromodynamics (QCD) phase diagram at finite temperature and baryon chemical potential is reviewed with special emphasis on the origin of various phases and their symmetry breaking patterns as mentioned in this paper.
Journal ArticleDOI
From hadrons to quarks in neutron stars: a review.
Gordon Baym,Tetsuo Hatsuda,Toru Kojo,Toru Kojo,Philip D. Powell,Philip D. Powell,Yifan Song,Tatsuyuki Takatsuka +7 more
TL;DR: In this article, the authors describe the structure of neutron stars constructed from the unified equations of states with crossover, and present the current equations of state-called "QHC18" for quark-hadron crossover-in a parametrized form practical for neutron star modeling.
Journal ArticleDOI
The phase diagram of nuclear and quark matter at high baryon density
Kenji Fukushima,Chihiro Sasaki +1 more
TL;DR: In this article, a review of theoretical approaches to explore the phase diagram of nuclear and quark matter at high baryon density is presented, with emphasis put on the relevance to quark-matter.

From hadrons to quarks in neutron stars: a review
Gordon Baym,Tetsuo Hatsuda,Toru Kojo,Toru Kojo,Philip D. Powell,Philip D. Powell,Yifan Song,Tatsuyuki Takatsuka +7 more
TL;DR: The structure of neutron stars constructed from the unified equations of states with crossover is described, and the parameters of effective quark models are constrained by neutron star mass and radii measurements, in particular favoring large repulsive density-density and attractive diquark pairing interactions.
