Complementarity between Gauge-Boson Compositeness and Asymptotic Freedom -- with scalar matter
Keiichi Akama, Takashi Hattori
We derive and solve the compositeness condition for the SU(N_c) gauge boson coupling with N_s scalar fields at the next-to-leading order in 1/N_s and the leading order in ln(Λ^2) (…
Brane Induced Gravity from its Dynamical Origin
Keiichi Akama
We develop a quantum theoretical formalism to derive the brane gravity from its origin -- brane-generating dynamics in higher dimensions. Based on it, we discuss characteristic pro…
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…
Unified Field Theory Induced on the Brane World
Keiichi Akama
We show how the gravity, gauge, and matter fields are induced on dynamically localized brane world.
Induced Field Theory on the Brane World
Keiichi Akama
We show how the gravity, gauge, and matter fields are induced on dynamically localized brane world (domain wall, vortex etc.). Solitonic solutions localized on a curved brane in ce…
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…
