Emergence of soft quark excitations by the coupling with a soft mode of the QCD critical point
Masakiyo Kitazawa, Teiji Kunihiro, Yukio Nemoto
We study the quark spectrum at nonzero temperature and density near the critical point (CP) of the chiral phase transition incorporating effects of the scalar- and pseudoscalar-den…
Possible generation of anomalously soft quark excitations at nonzero temperature: Nonhyperbolic dispersion of parapion and van Hove singularity
Masakiyo Kitazawa, Teiji Kunihiro, Yukio Nemoto
We study the quark spectrum at finite temperature near and above the pseudocritical temperature of the chiral phase transition incorporating the effects of the collective modes wit…
Quasifermion spectrum at finite temperature from coupled Schwinger-Dyson equations for a fermion-boson system
Masayasu Harada, Yukio Nemoto
We nonperturbatively investigate a fermion spectrum at finite temperature in a chiral invariant linear sigma model. Coupled Schwinger-Dyson equations for fermion and boson are deve…
How do diquark fluctuations and chiral soft modes affect di-lepton production in the deconfined phase?
Teiji Kunihiro, Masakiyo Kitazawa, Yukio Nemoto
We examine diquark fluctuations and chiral soft modes existing in the precritical region of color superconductivity and chiral transition, respectively, at finite temperature and d…
Spectral properties of massless and massive quarks coupled with massive boson at finite temperature
Masakiyo Kitazawa, Teiji Kunihiro, Kazuya Mitsutani +1
We study the properties of massless and massive quarks coupled with a scalar and pseudoscalar boson at finite temperature in Yukawa models at the one-loop order. The behavior of th…
Quasi-quark spectrum in the chiral symmetric phase from the Schwinger-Dyson equation
Masayasu Harada, Yukio Nemoto, Shunji Yoshimoto
We non-perturbatively study the fermion spectrum in the chiral symmetric phase from the Schwinger-Dyson equation with the Feynman gauge, in which we perform an analytic continuatio…
