Report

CP violation in long baseline neutrino oscillation experiments

Autor: Sakaguchi, Chise, Hattori, Toshihiko, Wakaizumi, Seiichi

We define a difference $D_{\rm CP}$ of the neutrino oscillation probability differences with matter effect for the CP-conjugate channels, divided by neutrino beam energy, taken between the two baselines $L = L_1$ and $L =L_2$ with $L_1/E_1 = L_2/E_2$

CP violation effect in long-baseline neutrino oscillation in the four-neutrino model

Autor: Hattori, Toshihiko, Hasuike, Tsutom, Wakaizumi, Seiichi

Publikováno v: Phys.Rev. D62 (2000) 033006

We investigate CP-violation effect in the long-baseline neutrino oscillation in the four-neutrino model with mass scheme of the two nearly degenerate pairs separated with the order of 1 eV, by using the data from the solar neutrino deficit, the atmos

CP violation in the semileptonic top decay in two-Higgs doublet model

Autor: Hasuike, Tsutom, Hattori, Toshihiko, Wakaizumi, Seiichi

Publikováno v: Phys.Rev. D58 (1998) 095008

CP violation in semileptonic top-quark decay is investigated by exactly using one charged- and three neutral-Higgs bosons obtained by solving the Higgs mass matrix in two-Higgs doublet model. The CP-violating up-down asymmetry of leptons from $W$ bos

CP Violation in $t\to W^+ b$ Decays in Two-Higgs Doublet Model

Autor: Hasuike, Tsutom, Hattori, Toshihiko, Hayashi, Toshio, Wakaizumi, Seiichi

Publikováno v: Z.Phys. C76 (1997) 127-132

Due to the large mass of top quark, CP violation in the top-quark decay is sensitive to the interactions mediated by Higgs bosons. We consider CP violation in $t\rightarrow W^+ b$ decay by calculating consistently in unitary gauge the CP-violating up
