  • Ginzburg-Landau Approach to Color Superconductivity

    IIDA Kei , BAYM Gordon , MATSUURA Taeko , HATSUDA Tetsuo

    We study, within Ginzburg-Landau theory, the equilibrium properties of a color super-conductor of three-flavor massless quarks near the transition temperature. We first draw the phase diagram in the s …

  • QCD Spectral Functions on the Lattice

    ASAKAWA Masayuki , HATSUDA Tetsuo

    Using the maximum entropy method (MEM), we extract the spectral functions in the scalar (S), pseudo-scalar (PS), vector (V), and axial-vector (AV) channels. Our results suggest that (i) the spectral f …

  • Chiral Symmetry Restoration and the σ-Meson(§6. Mesons in Nuclei,Possible Existence of the σ-Meson and Its Implications to Hadron Physics)

    HATSUDA Tetsuo , KUNIHIRO Teiji

    The σ-meson, which is at best a broad resonance in the vacuum, may suffer a substantial red-shift and appear as a soft and narrow collective mode at finite temperature and baryon densities. The physic …
