Higgs mass in the gauge-Higgs unification
Naoyuki Haba, Kazunori Takenaga, Toshifumi Yamashita
The gauge-Higgs unification theory identifies the zero mode of the extra dimensional component of the gauge field as the usual Higgs doublet. Since this degree of freedom is the Wi…
Neutron electric dipole moment and flavor changing interactions in supersymmetric theories
Gi-Chol Cho, Naoyuki Haba, Minako Honda
Supersymmetric contributions to the neutron electric dipole moment (EDM) are studied taking account of the flavor changing interactions. We found that the gluino contribution is se…
Supersymmetry breaking as the origin of flavor
Javier Ferrandis, Naoyuki Haba
We present an effective flavor model for the radiative generation of fermion masses and mixings based on a SU(5)xU(2) symmetry. We assume that the original source of flavor breakin…
Vacuum structure in 5D SO(10) GUT on
Naoyuki Haba, Toshifumi Yamashita
We study the vacuum structure in 5D SO(10) grand unified theory (GUT) compactified on orbifold, where SO(10) is broken into through the b…
Dynamical symmetry breaking in Gauge-Higgs unification of 5D SUSY theory
Naoyuki Haba, Toshifumi Yamashita
We study the dynamical symmetry breaking in the gauge-Higgs unification of the 5D SUSY theory, compactified on an orbifold, . This theory identifies Wilso…
Optimal-Observable Analysis of Possible New Physics Using the b-quark in gamma gamma -> tt -> bX
Bohdan Grzadkowski, Zenro Hioki, Kazumasa Ohkuma +1
We study possible anomalous top-quark couplings generated by SU(2) x U(1) gauge invariant dimension-6 effective operators, using the final b-quark momentum distribution in gamma ga…
