Polyakov loop extended NJL model with imaginary chemical potential
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +1
The Polyakov loop extended Nambu--Jona-Lasinio (PNJL) model with imaginary chemical potential is studied. The model possesses the extended symmetry that QCD does.…
Charged lepton and down-type quark masses in SU(1,1) model and the structure of higgs sector
Kenzo Inoue, Naoki Yamatsu
The simplest noncompact group SU(1,1),when introduced as a symmetry group of the generations of quarks and leptons in the framework of a vector-like theory, gives an excellent view…
Critical endpoint in the Polyakov-loop extended NJL model
Kouji Kashiwa, Hiroaki Kouno, Masayuki Matsuzaki +1
The critical endpoint (CEP) and the phase structure are studied in the Polyakov-loop extended Nambu--Jona-Lasinio model in which the scalar type eight-quark (σ^4) interaction and t…
Four- and Five-Body Scattering Calculations
Emiko Hiyama, Hideo Suganuma, Masayasu Kamimura
We study the five-quark system in the standard non-relativistic quark model by solving the scattering problem. Using the Gaussian Expansion Method (GEM), we perform…
Effects of a multi-quark interaction on color superconducting phase transition in an extended NJL model
Kouji Kashiwa, Masayuki Matsuzaki, Hiroaki Kouno +1
We study the interplay of the chiral and the color superconducting phase transitions in an extended Nambu--Jona-Lasinio model with a multi-quark interaction that produces the nonli…
Holographic Construction of Technicolor Theory
Takayuki Hirayama, Koichi Yoshioka
We construct a dual description of technicolor theory based on the D4/D8 brane configuration. A strongly-coupled technicolor theory is identified as the effective theory on D-brane…
