Phenomenology of Harmless Family Gauge Bosons to $K^{0}$ - $K ˉ^{0}$ Mixing

Yoshio Koide

When we try to consider family gauge bosons with a lower energy scale, a major obstacle is constraints from the observed $P^{0}$ - $P ˉ^{0}$ mixings ( $P^{0} = K^{0}, D^{0}, B^{0}, B_{s}^{0}$ ). Agai…

U(3) $\times$ [U(1)] $^{3}$ Model and Visible Family Gauge Boson Effects

Yoshio Koide

A U(3) family gauge boson model is investigated based on U(3) $\times$ [U(1)] $^{3}$ gauge symmetry. In this model, of nine U(3) family gauge bosons $A_{i}^{j}$ , those with $i = j$ are co…

Yukawaon Model with Anomaly Free Set of Quarks and Leptons in a U(3) Family Symmetry

Yoshio Koide, Hiroyuki Nishiura

In the so-called "yukawaon" model, the (effective) Yukawa coupling constants $Y_{f}^{e f f}$ are given by vacuum expectation values (VEVs) of scalars $Y_{f}$ (yukawaons) with $3 \times 3$ …

Effective Valence Quark Model and a Possible Dip in $d B r (B \to K ℓ ℓ ˉ) / d q^{2}$

Hiroyuki Ishida, Yoshio Koide

In rare $B$ meson decays $B \to K ℓ^{+} ℓ^{-}$ , a possible contribution of $ℓ^{+} ℓ^{-}$ emission via photon from the "spectator" quark $q$ ( $q = u, d$ ) in the $B$ meson $(q…

Neutrino Mass Matrix Model with a Bilinear Form

Yoshio Koide, Hiroyuki Nishiura

A neutrino mass matrix model with a bilinear form $M_{ν} = k_{ν} (M_{D} M_{R}^{- 1} M_{D}^{T})^{2}$ is proposed within the framework of the so-called yukawaon model, which has been proposed for the…
