In the paper, we presented the picture that we live in a “brane world” (in the presentday terminology) i.e. in a dynamically localized 3-brane in a higher dimensional space. We adopt, as an example,… (More)

This talk is based on a work done in collaboration with A. Akabane, T. Hattori, K. Katsuura, and H. Mukaida.[1] Here I would like to show how the gravitational, gauge and matter field theories are… (More)

We show that the coupling-constant of a quantum-induced composite field is scale invariant due to its compositeness condition. It is first demonstrated in next-to-leading order in 1/N in typical… (More)

Assuming naturalness that the quantum corrections to the mass should not exceed the order of the observed mass, we derive and apply model-independent bounds on the anomalous magnetic moments and… (More)

We derived and solved the compositeness condition in the Nambu-Jona-Lasinio model at the next-to-leading order in 1/N , and obtained the expressions for the effective coupling constants in terms of… (More)

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 of the… (More)

We derive and solve the compositeness condition for the SU(Nc) gauge boson coupling with Ns scalar fields at the next-to-leading order in 1/Ns and the leading order in lnΛ (Λ is the compositeness… (More)

We show that the renormalization group β functions in the Nambu-JonaLasinio model identically vanish in all order due to the compositeness condition. Accordingly the effective coupling constants are… (More)

We investigate the renormalization group flow of the Yukawa model with a fixed momentum cutoff at the leading order in 1/N , where N is the number of the fermion species. We demonstrate the scale… (More)
