Lovelock Gravity with Spontaneous Dimensional Breaking

Autor: Nishida, Kouzou

We consider D-dimensional Lovelock gravity with only one term of higher-order Lovelock Lagrangian densities, and show that a product of Minkowski space-time and n-spheres is its vacuum solution. The most interesting feature of our model is that the s

A Vacuum Solution with Torsion in Higher-Derivative Gravity

Autor: Nishida, Kouzou

In this paper, we provide a vacuum solution with torsion in quadratic Riemann-curvature gravity. Physically, the solution means that vacuum can have a nonzero vacuum field with large torsion. We show that the Einstein-Hilbert action can be derived if

A Generalized Gauge Theory of Gravity

Autor: Nishida, Kouzou

In this paper, we discuss a gravitational theory based on the generalized gauge field. Our Lagrangian is invariant not only under local Lorentz transformation and the ordinary gauge transformation but also under a new gauge transformation. We show th

A Phenomenological Formula for KM Matrix

Autor: Nishida, Kouzou, Sogami, Ikuo S.

Publikováno v: Prog.Theor.Phys.96:857-862,1996

We propose a phenomenological formula relating the Kobayashi-Maskawa matrix $V_{KM}$ and quark masses in a form $(m_d,\ m_s,\ m_b)\propto (m_u,\ m_c,\ m_t)V_{KM}$. The formula agrees with experimental data well and has an interesting geometric pictur

Renormalization Group Effects on the Mass Relation Predicted by the Standard Model with Generalized Covariant Derivatives

Autor: Shinohara, Tadatomi, Nishida, Kouzou, Tanaka, Hajime, Sogami, Ikuo S.

Publikováno v: Prog.Theor.Phys. 96 (1996) 1179-1188

Renormalization group analysis is made on the relation $m_{\rm H} \simeq \sqrt{2}m_t$ for masses of the top quark and the Higgs boson, which is predicted by the standard model based on generalized covariant derivatives with gauge and Higgs fields. Th
