Testing the nature of the resonance through photoproduction
L. Roca, E. Oset, H. Toki
Recent studies within the framework of chiral unitary theory produce the resonance, among several others, as a dynamically generated resonance from the interaction of the…
Chromomagnetic Catalysis of Chiral Symmetry Breaking and Color Superconductivity
D. Ebert, V. V. Khudyakov, K. G. Klimenko +2
It is shown in the framework of an extended NJL model with two flavors that some types of external chromomagnetic field induce the dynamical chiral or color symmetry breaking even…
The phi --> pi^+ pi^- and phi radiative decays within a chiral unitary approach
E. Oset, S. Hirenzaki, E. Marco +3
We report on recent results on the decay of the phi into pi^+ pi^- and phi radiative decays into pi^0 pi^0 gamma and pi^0 eta gamma, which require the consideration of the final st…
Axial Currents of Virtual Charm in Light Quark Processes
F. Araki, M. Musakhanov, H. Toki
The systematic investigations of the role of the virtual charm axial currents in the decay of -mesons to and the spin structure of the nucleon are performed. We reduce…
Behavior of monopole trajectories in the instanton and anti-instanton system at finite temperature
Fumiaki Araki, Hideo Suganuma, Hiroshi Toki
We study the connection between monopoles and instantons in the Polyakov-like gauge, and the behavior of the monopole trajectories generated by instantons at finite temperature. Th…
Properties of the QCD vacuum in the dual Ginzburg-Landau theory
S. Umisedo, H. Toki, H. Suganuma
We study the properties of the QCD vacuum in the dual Ginzburg-Landau theory, where QCD-monopole condensation leads to the linear confinement potential. Using the effective potenti…
