The Role and Detectability of the Charm Contribution to Ultra High Energy Neutrino Fluxes
Raj Gandhi, Abhijit Samanta, Atsushi Watanabe
It is widely believed that charm meson production and decay may play an important role in high energy astrophysical sources of neutrinos, especially those that are baryon-rich, pro…
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…
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…
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.…
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…
