NNI Quark-Lepton Mass Matrices in SUSY SU(5) GUT
Toshiaki Ito, Naotoshi Okamura, Morimitsu Tanimoto
We propose the Fritzsch-Branco-Silva-Marcos type fermion mass matrix, which is a typical texture in the nearest-neighbor interaction form, in SU(5) GUT. By evolution of the mass ma…
New Possibility of Solving the Problem of Lifetime Ratio
Toshiaki Ito, Masahisa Matsuda, Yoshimitsu Matsui
We discuss the problem of the large discrepancy between the observed lifetime ratio of to and the theoretical prediction obtained by the heavy quark effective theory. A…
The Unitarity Triangle on the First Quadrant and the Quark Mass Matrices in the Nearest-Neighbor Interaction Basis
Toshiaki Ito
The unitarity triangle on the first quadrant in the plane is discussed in the framework of the quark mass matrices in the NNI basis. If the quark mass matrices of the up-type…
The Ξ_Q - Ξ_Q' Mixing and Heavy Baryon Masses
Toshiaki Ito, Yoshimitsu Matsui
We examine the mixing and heavy baryon masses in the heavy quark effective theory with the $\mq$ corrections. In the conventional baryon assignment, we obtain the mixi…
The Unitarity Triangle and Quark Mass Matrices on the NNI Basis
Toshiaki Ito, Morimitsu Tanimoto
We examine the unitarity triangle of the KM matrix by using the general quark mass matrices on the NNI basis. The Fritzsch anzätz is modified by introducing four additional paramet…
