Probabilistic Naturalness Measure for Dipole Moments due to New Physics
Keiichi Akama, Takashi Hattori, Kazuo Katsuura
We introduce a probabilistic measure of naturalness (naturalness level) to fix naturalness bounds quantitatively. It is applied to the anomalous magnetic moments and the electric d…
A Dynamical Origin of the Mass Hierarchy among Neutrinos, Charged Leptons, and Quarks
Keiichi Akama, Kazuo Katsuura
We propose a dynamical mass-generation scenario which naturally realizes the mass hierarchy among the neutrinos, charged leptons and quarks, where the mass is dominated by the self…
Compositeness Condition
Keiichi Akama
By solving the compositeness condition, under which the Yukawa-type model coincides the NJL type model, we obtain the expressions for the effective coupling constants in terms of t…
Compositeness Condition in the Nambu-Jona-Lasinio Model
Keiichi Akama
The Nambu-Jona-Lasinio model is the special case of the renormalized Yukawa model with the compositeness condition. We use it to calculate the effective coupling constants in terms…
