Bulk Standard Model in the Randall-Sundrum Background

- S. Chang, J. Hisano, H. Nakano, N. Okada, M. Yamaguchi
- Physics
- 24 December 1999

We discuss issues in an attempt to put the standard model (SM) in five-dimensional anti\char21{}de Sitter spacetime compactified on ${S}^{1}{/Z}_{2}.$ The recently proposed approach to the gauge… Expand

Improving the Effective Potential Multi-Mass-Scale Case

- M. Bandō, T. Kugo, N. Maekawa, H. Nakano
- Physics
- 12 October 1992

Previously proposed procedure for improving the effective potential by using renormalization group equation (RGE) is generalized so as to be applicable to any system containing several different mass… Expand

Improving the effective potential

- M. Bandō, T. Kugo, N. Maekawa, H. Nakano
- Physics
- 12 October 1992

Abstract A g ene ral procedure is presented how to improve the effective potential by using the renormalization group equation (RGE) in the MS scheme. If one knows the L-loop effective potential and… Expand

Anomalous U(1) D-term contribution in type I string models

- T. Higaki, Y. Kawamura, Tatsuo Kobayashi, H. Nakano
- Physics
- 11 August 2003

We study the D-term contribution for anomalous $U(1)$ symmetries in type I string models and derive a general formula for the D-term contribution, assuming that the dominant source of supersymmetry… Expand

Yukawa hierarchy transfer from the superconformal sector and degenerate sfermion masses

- Tatsuo Kobayashi, H. Nakano, H. Terao
- Physics
- 4 July 2001

We propose a new type of supersymmetric models coupled to superconformal field theories (SCFT's), leading simultaneously to hierarchical Yukawa couplings and completely degenerate sfermion masses. We… Expand

Nontriviality of Gauge-Higgs-Yukawa System and Renormalizability of Gauged NJL Model

- M. Harada, Y. Kikukawa, T. Kugo, H. Nakano
- Physics
- 29 July 1994

In the leading order of a modified 1/Nc expansion, we show that a class of gauge-Higgs-Yukawa systems in four dimensions give non-trivial and well-defined theories in the continuum limit. The… Expand

Neutrino mass and proton decay in a U(1)R-symmetric model

- Yusuke Morita, H. Nakano, T. Shimomura
- Physics
- 18 December 2012

We study a U(1) R symmetric extenstion of supersymmetric standard model with supersymmetry breaking in the visible as well as hidden sectors. Specifically we study U(1) R breaking effects… Expand
