The low-lying Scalar Mesons and Related Topics
T. Kunihiro, S. Muroya, A. Nakamura +3
After presenting the motivations to explore the low-lying scalar mesons such as the , and in the unquenched as well as quenched lattice QCD, we review the works done b…
Towards a Theory of Entropy Production in the Little and Big Bang
Teiji Kunihiro, Berndt Muller, Akira Ohnishi +1
We propose a broadly applicable formalism for the description of coarse grained entropy production in quantum mechanical processes. Our formalism is based on the Husimi transform o…
Another chiral critical end-point induced by neutral color superconductivity
Zhao Zhang, Kenji Fukushima, Teiji Kunihiro
This paper has been withdrawn by the authors, due to it's incompleteness.
Number of the QCD critical points with neutral color superconductivity
Zhao Zhang, Kenji Fukushima, Teiji Kunihiro
We investigate the effect of the electric-charge neutrality in equilibrium on the chiral phase transition by solving the chiral and diquark condensates in the two-flavor Nambu-…
In-medium Pion and Partial Restoration of Chiral Symmetry
D. Jido, T. Hatsuda, T. Kunihiro
The partial restoration of chiral symmetry in nuclear medium is investigated in a model independent way by exploiting operator relations in QCD. An exact sum rule is derived for th…
Axial charges of N(1535) and N(1650) in lattice QCD with two flavors of dynamical quarks
Toru T. Takahashi, Teiji Kunihiro
We show the first lattice QCD results on the axial charge of and . The measurements are performed with two flavors of dynamical quarks employi…
