Renormalization group equations in a model of generalized hidden local symmetry and restoration of chiral symmetry
Yoshimasa Hidaka, Osamu Morimatsu, Munehisa Ohtani
We study possible restoration patterns of chiral symmetry in a generalized hidden local symmetry model, which is a low energy effective theory of QCD including pseudo-scalar, vecto…
Color Ferromagnetic Quark Matter in Neutron Stars
Aiichi Iwazaki, Osamu Morimatsu, Tetsuo Nishikawa +1
We show that color ferromagnetic phase of quark matter is energetically more favored than color superconducting phases in neutron stars. Namely, increasing baryon density in neutro…
Coupled QCD sum rules for positive and negative-parity nucleons
Yoshihiko Kondo, Osamu Morimatsu, Tetsuo Nishikawa
A new approach of the QCD sum rule is proposed in which positive and negative-parity baryons couple with each other. With positive and negative-parity states explicitly taken into…
Axial vector tetraquark with S=+2
Y. Kanada-En'yo, O. Morimatsu, T. Nishikawa
Possibility of an axial vector isoscalar tetraquark with is discussed. If the pentaquark has the configuration,…
