Inflation from the Finite Scale Gauged Nambu-Jona-Lasinio Model
Tomohiro Inagaki, Sergei D. Odintsov, Hiroki Sakamoto
The possibility to construct an inflationary universe scenario for the finite-scale gauged Nambu-Jona-Lasinio model is investigated. This model can be described by the Higgs-Yukawa…
Non-Minimal Two-Loop Inflation
Tomohiro Inagaki, Ryota Nakanishi, Sergei D. Odintsov
We investigate the chaotic inflationary model using the two-loop effective potential of a self-interacting scalar field theory in curved spacetime. We use the potential which conta…
Could the dynamical Lorentz symmetry breaking induce the superluminal neutrinos?
Shin'ichi Nojiri, Sergei D. Odintsov
The toy fermion model coupled with Lagrange multiplier constraint field is proposed. The possibility of superluminal neutrino propagation as result of dynamical Lorentz symmetry br…
Dynamical symmetry restoration for a higher-derivative four-fermion model in an external electromagnetic field
E. Elizalde, S. P. Gavrilov, S. D. Odintsov +1
A four-fermion model with additional higher-derivative terms is investigated in an external electromagnetic field. The effective potential in the leading order of large-N expansion…
Finite Grand Unified Theories and Inflation
Seiji Mukaigawa, Taizo Muta, Sergei D. Odintsov
A class of finite GUTs in curved spacetime is considered in connection with the cosmological inflation scenario. It is confirmed that the use of the running scalar-gravitational co…
