Abstract

Chiral restoration phase transition in hot and/or dense hadronic matter is discussed in terms of the BR scaling based on chiral symmetry and scale anomaly of QCD. The precise connection between the scalar field that figures in the trace anomaly and the sigma field that figures in the linear a model is established. It is suggested that in hot and/or dense medium, the nonlinear a model linearizes. with the help of a dilaton to a linear {sigma} model with medium-renormalized constants. The relevance of Georgi`s vector symmetry and/or Weinberg`s ``mended symmetry`` in chiral restoration is pointed out. Some striking consequences for relativistic heavy-ion collisions and dense matter in compact stars following stellar collapse are discussed.

Finite-temperature corrections in the dilated chiral quark model

Technical Report Kim, Y; Lee, Hyun; Rho, M

We calculate the finite-temperature corrections in the dilated chiral quark model using the effective potential formalism. Assuming that the dilaton limit is applicable at some short length scale, we interpret the results to represent the behavior of hadrons in dense and hot matter. We obtain the scaling law, f{sub {pi}}(T)/f{sub {pi}} = m{sub Q}(T)/m{sub Q} {approx_equal} m{sub {sigma}}(T)/m{sub {sigma}}while we argue, using PCAC, that pion mass does not scale within the temperature range involved in our Lagrangian. It is found that the hadron masses and the pion decay constant drop faster with temperature in the dilated chiral quark model thanmore »« less

Three-flavor chiral phase structure in hot and dense QCD matter

Journal Article Schaefer, B; Wagner, M - Physical Review. D, Particles Fields

Chiral symmetry restoration at nonzero temperature and quark densities are investigated in the framework of a linear sigma model with N{sub f}=3 light quark flavors. After the derivation of the grand potential in mean-field approximation, the nonstrange and strange condensates, the in-medium masses of the scalar and pseudoscalar nonets are analyzed in hot and dense medium. The influence of the axial anomaly on the nonet masses and the isoscalar mixings on the pseudoscalar {eta}-{eta}{sup '} and scalar {sigma}(600)-f{sub 0}(1370) complex are examined. The sensitivity of the chiral phase transition as well as the existence and location of a critical endmore »« less

Chiral Lagrangian with broken scale: Testing the restoration of symmetries in astrophysics and in the laboratory

Journal Article Bonanno, Luca; Drago, Alessandro - Physical Review. C, Nuclear Physics

We study matter at high density and temperature using a chiral Lagrangian in which the breaking of scale invariance is regulated by the value of a scalar field, called dilaton [E. K. Heide, S.

Chiral thermodynamics of dense hadronic matter

Journal Article Sasaki, C - Physics of Atomic Nuclei

We discuss phases of hot and dense hadronic matter using chiral Lagrangians. A two-flavored parity doublet model constrained by the nuclear matter ground state predicts chiral symmetry restoration. The model thermodynamics is shown within the mean-field approximation. A field-theoretical constraint on possible phases from the anomaly matching is also discussed.
