Anomalies of Discrete Symmetries and Gauge Coupling Unification
Takeshi Araki
The anomaly of a discrete symmetry is defined as the Jacobian of the path-integral measure. Assuming that the anomaly at low energies is cancelled by the Green-Schwarz (GS) mechani…
The SUSY Flavor Problem, Proton Decay and Discrete Family Symmetry
Etsuko Itou, Yuji Kajiyama, Jisuke Kubo
We consider a supersymmetric extension of the standard model, which possess a family symmetry based on a binary dihedral group Q6, and investigate the consequences of the family sy…
Magnetic component of Yang-Mills plasma
M. N. Chernodub, V. I. Zakharov
Confinement in non-Abelian gauge theories is commonly ascribed to percolation of magnetic monopoles, or strings in the vacuum. At the deconfinement phase transition the condensed m…
Anomaly of discrete family symmetries and gauge coupling unification
Takeshi Araki
Anomaly of discrete symmetries can be defined as the Jacobian of the path-integral measure. We assume that an anomalous discrete symmetry at low energy is remnant of an anomaly fre…
D6 Family Symmetry and Cold Dark Matter at LHC
Yuji Kajiyama, Jisuke Kubo, Hiroshi Okada
We consider a non-supersymmetric extension of the standard model with a family symmetry based on D6 Z2 Z2, where one of Z2's is exactly conserved. This Z2 forbids the tree-level ne…
Neutrino masses and CDM in a non-supersymmetric model
Jisuke Kubo, Daijiro Suematsu
We propose a model for neutrino mass generation based on both the tree-level seesaw mechanism with a single right-handed neutrino and one-loop radiative effects in a non-supersymme…
D_{s0}^+(2317) as an iso-triplet four-quark meson
Kunihiko Terasaki
Although assigning D_{s0}^+(2317) to the I_3=0 component of iso-triplet four-quark mesons is favored by experiments, its neutral and doubly charged partners have not yet been obser…
Supersymmetric extra U(1) models with a singlino dominated LSP
Satoshi Nakamura, Daijiro Suematsu
We investigate phenomenology related to the neutral fields in supersymmetric models with an extra U(1) derived from . Our study is concentrated into the models which have a si…
Vector form factor in K_l3 semileptonic decay with two flavors of dynamical domain-wall quarks
C. Dawson, T. Izubuchi, T. Kaneko +2
We calculate the vector form factor in K \to πl νsemileptonic decays at zero momentum transfer f_+(0) from numerical simulations of two-flavor QCD on the lattice. Our simulations a…
SUSY breaking based on Abelian gaugino kinetic term mixings
Daijiro Suematsu
We present a SUSY breaking scenario based on Abelian gaugino kinetic term mixings between hidden and observable sectors. If an extra U(1) gaugino in the observable sector obtains a…
Dynamical realization of democratic Yukawa matrices and alignment of A-terms
Tatsuo Kobayashi, Yuji Omura, Haruhiko Terao
We study realization of the democratic form of Yukawa matrices by infrared fixed points. We investigate renormalization-group flows of Yukawa couplings in models with a single Yuka…
Production of neutral and doubly charged partners of D_{s0}^+(2317)
Kunihiko Terasaki
Production of neutral and doubly charged partners, and , of as a charm-strange four-quark meson is studied in relation to observations…
Cold Dark Matter, Radiative Neutrino Mass, mu to e gamma, and Neutrinoless Double Beta Decay
Jisuke Kubo, Ernest Ma, Daijiro Suematsu
Two of the most important and pressing questions in cosmology and particle physics are: (1) What is the nature of cold dark matter? and (2) Will near-future experiments on neutrino…
Fine-tuning in gauge mediated supersymmetry breaking models and induced top Yukawa coupling
Tatsuo Kobayashi, Haruhiko Terao, Akito Tsuchiya
It is shown that fine-tuning of the Higgs parameters stronger than a few % is required at the best in the models with gauge mediated supersymmetry breaking. With the aim of solving…
