Chiral phase transition in three-flavor QCD from lattice QCD [PDF]
Physical Review D, 2021 We analyze the pseudo-critical behavior of three-flavor QCD using highly improved staggered quarks (HISQ) on lattices with temporal extent N τ = 8 and for quark masses corresponding to a pseudoscalar Goldstone mass in the range 80 MeV < ∼ m π < ∼ 140 MeV.

Lattice Constraints on the QCD Chiral Phase Transition at Finite Temperature and Baryon Density [PDF]
Symmetry, 2021 The thermal restoration of chiral symmetry in QCD is known to proceed by an analytic crossover, which is widely expected to turn into a phase transition with a critical endpoint as the baryon density is increased.

The QCD chiral phase transition for different numbers of quark flavours [PDF]
Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2021 We present results from a comprehensive study of the location of the chiral critical surface, which separates regions of first-order chiral transitions from analytic crossovers, in the bare parameter space of lattice QCD with unimproved staggered ...

New interpretation of the chiral phase transition: Violation of the trilemma in QCD [PDF]
Physical Review D, 2021 We find that the chiral phase transition (chiral crossover) in QCD at physical point is triggered by big imbalance among three fundamental quantities essential for the QCD vacuum structure: susceptibility functions for the chiral symmetry, axial symmetry,

Chiral restoration of strange baryons [PDF]
EPJ Web of Conferences, 2022 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 under neutron star conditions within a single model, but without adding quark

Chiral phase transitions of helical matter [PDF]
Physical Review D, 2021 We study the thermodynamics of helical matter, namely quark matter in which a net helicity, $n_H$, is in equilibrium. Interactions are modeled by the renormalized quark-meson model with two flavors of quarks. Helical density is described within the grand-canonical ensemble formalism via a chemical potential, $ _H$.

Detecting scale anomaly in chiral phase transition of QCD: new critical endpoint pinned down
Journal of High Energy Physics, 2021 Violation of scale symmetry, scale anomaly, being a radical concept in quantum field theory, is of importance to comprehend the vacuum structure of QCD, and should potentially contribute to the chiral phase transition in thermal QCD, as well as the ...

Enhanced yield ratio of light nuclei in heavy ion collisions with a first-order chiral phase transition [PDF]
European Physical Journal A, 2020 Using a transport model that includes a first-order chiral phase transition between the partonic and the hadronic matter, we study the development of density fluctuations in the matter produced in heavy ion collisions as it undergoes the phase transition,

Analytic study on chiral phase transition in holographic QCD [PDF]
Journal of High Energy Physics, 2020 The chiral symmetry breaking (χsb) is one of the most fundamental problems in QCD. In this paper, we calculate quark condensation analytically in a holographic QCD model dual to the Einstein-Maxwell-Dilaton (EMD) system coupled to a probe scalar field ...
