Runge-Lenz Vector as a 3d Projection of SO(4) Moment Map in Phase Space

Hitoshi Ikemori, Shinsaku Kitakado, Yoshimitsu Matsui +1

We show, using the methods of geometric algebra, that Runge-Lenz vector in the Kepler problem is a 3-dimensional projection of SO(4) moment map that acts on the phase space of 4-di…

Mixing Angle of in Heavy Quark Effective Therory

Yoshimitsu Matsui

The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angle of hadron states in a heavy quark, such as the charm quark (c) and the bottom quark (b). By…

Equivariance on Discrete Space and Yang-Mills-Higgs Model

Hitoshi Ikemori, Shinsaku Kitakado, Yoshimitsu Matsui +2

We introduce the basic equivariant quantity in the gauge theory on the noncommutative descrete space, which plays an important role for the equivariant dimensional redu…

Are lepton flavor mixings in the democratic mass matrix stable against quantum corrections?

N. Haba, Y. Matsui, N. Okamura +1

We investigate whether the lepton flavor mixing angles in the so-called democratic type of mass matrix are stable against quantum corrections or not in the minimal supersymmetric s…

Analytic Solutions to the RG Equations of the Neutrino Physical Parameters

N. Haba, Y. Matsui, N. Okamura

In the case of two generation neutrinos, the energy-scale dependence of the lepton-flavor mixing matrix with Majorana phase can be governed by only one parameter r, which is the ra…

The effect of Majorana phase in degenerate neutrinos

N. Haba, Y. Matsui, N. Okamura +1

There are physical Majorana phases in the lepton flavor mixing matrix when neutrinos are Majorana fermions. In the case of two degenerate neutrinos, the physical Majorana phase pla…
