General Solutions of Braneworlds under the Schwarzschild Ansatz
Keiichi Akama, Takashi Hattori, Hisamitsu Mukaida
General solutions for braneworld dynamics coupled with the bulk Einstein equation are derived under the Schwarzschild ansatz. They relate the brane metric to the exterior configura…
Scalar-Composite Model in 6 - 2εDimensions
Keiichi Akama, Takashi Hattori
We study the model of a composite-scalar made of a pair of scalar fields in 6-2 epsilon dimensions, using equivalence to the renormalizable three-elementary-scalar model under the…
Exact Scale Invariance of Composite-Field Coupling Constants
Keiichi Akama, Takashi Hattori
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…
A Scale Invariance due to Compositeness Condition in the Induced Gauge Theory
Akira Akabane, Keiichi Akama
The scale invariance of the coupling constant in the induced gauge theory due to its compositeness condition is demonstrated in the renormalization group flow of the finite-cutoff…
Renormalization Group Flow in the Cutoff Yukawa Model and a Scale Invariance in the Nambu-Jona-Lasinio Model
Keiichi Akama
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 demonst…
Induced Field Theory on the Brane World - Gravity, Extrinsic Curvature, and Gauge Fields
Keiichi Akama, Takashi Hattori
We show how the gravity, extrinsic curvature, and gauge field theories are induced on dynamically localized brane world. They should obey the Gauss-Codazzi-Ricci equation in additi…
