Meson mass at real and imaginary chemical potentials
Kouji Kashiwa, Masayuki Matsuzaki, Hiroaki Kouno +2
The chemical-potential dependence of pi and sigma meson masses is analyzed at both real and imaginary chemical potentials, and , by using the Polyakov-…
Vector-type four-quark interaction and its impact on QCD phase structure
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +2
Effects of the vector-type four-quark interaction on QCD phase structure are investigated in the imaginary chemical potential region, by using the Polyakov-loop extended Nambu-Jona…
Strong CP Problem and the Natural Hierarchy of Yukawa Couplings
Kenzo Inoue, Naoki Yamatsu
A possible solution to the strong CP problem is presented without using an axion. The model is based on the framework of the supersymmetric vectorlike theory with the spontaneous b…
Correlations among discontinuities in QCD phase diagram
Kouji Kashiwa, Yuji Sakai, Hiroaki Kouno +2
We show, in general, that when a discontinuity of either zeroth-order or first-order takes place in an order parameter such as the chiral condensate, discontinuities of the same or…
Phase diagram in the imaginary chemical potential region and extended Z3 symmetry
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +1
Phase transitions in the imaginary chemical potential region are studied by the Polyakov loop extended Nambu-Jona-Lasinio (PNJL) model that possesses the extended Z3 symmetry. The…
Multi-Higgs Mass Spectrum in Gauge-Higgs Unification
Kentaro Kojima, Kazunori Takenaga, Toshifumi Yamashita
We study an SU(2) supersymmetric gauge model in a framework of gauge-Higgs unification. Multi-Higgs spectrum appears in the model at low energy. We develop a useful perturbative ap…
