Novel Collective Excitations and the Quasi-Particle Picture of Quarks Coupled with a Massive Boson at Finite Temperature
Masakiyo Kitazawa, Teiji Kunihiro, Yukio Nemoto
Motivated by the observation that there may exist hadronic excitations even in the quark-gluon plasma (QGP) phase, we investigate how the properties of quarks, especially within th…
Derivation of Covariant Dissipative Fluid Dynamics in the Renormalization-group Method
K. Tsumura, T. Kunihiro, K. Ohnishi
We derive generic relativistic hydrodynamical equations with dissipative effects from the underlying Boltzmann equation in a mechanical and systematic way on the basis of so called…
Quasiparticle picture of quarks near chiral transition at finite temperature
Masakiyo Kitazawa, Teiji Kunihiro, Yukio Nemoto
We investigate, using a chiral effective model, the quark spectrum in the critical region of the chiral transition focusing on the effect of the possible mesonic excitations in the…
Thermal unpairing transitions affected by neutrality constraints and chiral dynamics
H. Abuki, T. Kunihiro
We discuss the phase structure of homogeneous quark matter under the charge neutrality constraints, and present a unified picture of the thermal unpairing phase transitions for a w…
