CP Violation in B_s Mixing in the SUSY SU(5) GUT with Right-handed Neutrinos
Junji Hisano, Yasuhiro Shimizu
It is recently announced by the {\bf Ut}{\it fit} collaboration that the CP phase of the mixing amplitude, , deviates more than from the standard-model predict…
Upperbound on Squark Masses in Gauge-Mediation Model with Light Gravitino
Junji Hisano, Minoru Nagai, Shohei Sugiyama +1
We examine stabilities of our supersymmetry-breaking false vacuum in a low-energy direct gauge mediation model of SUSY breaking. The stability required in the high-temperature earl…
"Flavored" Electric Dipole Moments in Supersymmetric Theories
J. Hisano, M. Nagai, P. Paradisi
The Standard Model (SM) predictions for the hadronic electric dipole moments (EDMs) are well far from the present experimental resolutions, thus, the EDMs represent very clean prob…
Stability of Metastable Vacua in Gauge Mediated SUSY Breaking Models with Ultra Light Gravitino
Junji Hisano, Minoru Nagai, Masato Senami +1
Recently Murayama and Nomura proposed a simple scheme to construct the gauge mediation models, using metastable supersymmetry breaking vacua. It has a possibility to predict the ul…
Revisiting Signature of Minimal Gauge Mediation
Junji Hisano, Yasuhiro Shimizu
We revisit phenomenology of the minimal gauge-mediated model. This model is motivated from the SUSY CP and flavor problems. A specific feature of this model is that \tanβis natural…
Electric Dipole Moments in PseudoDirac Gauginos
Junji Hisano, Minoru Nagai, Tatsuya Naganawa +1
The SUSY CP problem is one of serious problems in construction of realistic supersymmetric standard models. We consider the problem in a framework in which adjoint chiral multiplet…
