Electroweak Symmetry Breaking in Supersymmetric Gauge-Higgs Unification Models
Kiwoon Choi, Naoyuki Haba, Kwang-Sik Jeong +3
We examine the Higgs mass parameters and electroweak symmetry breaking in supersymmetric orbifold field theories in which the 4-dimensional Higgs fields originate from higher-dimen…
Probing Anomalous Top-Quark Couplings Induced by Dim.6 Operators at Photon Colliders
Bohdan Grzadkowski, Zenro Hioki, Kazumasa Ohkuma +1
Possible anomalous top-quark couplings induced by SU(2) x U(1) gauge-invariant dimension-6 effective operators were studied in the process of t t-bar productions and decays at pola…
Classification and dynamics of equivalence classes in SU(N) gauge theory on the orbifold
Naoyuki Haba, Yutaka Hosotani, Yoshiharu Kawamura
The dynamical determination of the boundary conditions in SU(N) gauge theory on the orbifold is investigated. We classify the equivalence classes of the boundary conditio…
Anisotropic spin fluctuations in heavy-fermion superconductor CeCoIn5: In-NQR and Co-NMR studies
Y. Kawasaki, S. Kawasaki, M. Yashima +7
We report In-NQR and Co-NMR experiments of CeCoIn that undergoes a superconducting transition with a record high = 2.3 K to date among heavy-fermion superconductors…
Fat Branes, Orbifolds and Doublet-Triplet Splitting
Naoyuki Haba, Nobuhito Maru
A simple higher dimensional mechanism of the doublet-triplet splitting is presented in a five dimensional supersymmetric SU(5) GUT on . The splitting of multiplets is real…
Gapless Magnetic and Quasiparticle Excitations due to the Coexistence of Antiferromagnetism and Superconductivity in CeRhIn : A study of In-NQR under Pressure
S. Kawasaki, T. Mito, Y. Kawasaki +5
We report systematic measurements of ac-susceptibility, nuclear-quadrupole-resonance spectrum, and nuclear-spin-lattice-relaxation time () on the pressure ()- induced heavy…
