Neutron Electric Dipole Moment Induced by the Strangeness Revisited
Kaori Fuyuto, Junji Hisano, Natsumi Nagata
We have revisited the calculation of the neutron electric dipole moment in the presence of the CP-violating operators up to dimension five based on the chiral perturbation theory.…
Direct Search of Dark Matter in High-Scale Supersymmetry
Junji Hisano, Koji Ishiwata, Natsumi Nagata
We study direct detection of dark matter in supersymmetric (SUSY) model where most of SUSY particles have very high-scale masses beyond the weak scale. In the scenario, Wino-like o…
A calculation for vector dark matter direct detection
Natsumi Nagata
We evaluate the elastic scattering cross section of vector dark matter with nucleon based on the method of effective field theory. The dark matter is assumed to behave as a vector…
Reevaluation of Neutron Electric Dipole Moment with QCD Sum Rules
Junji Hisano, Jeong Yong Lee, Natsumi Nagata +1
We study the neutron electric dipole moment in the presence of the CP-violating operators up to the dimension five in terms of the QCD sum rules. It is found that the OPE calculati…
Enhancement of Proton Decay Rates in Supersymmetric SU(5) Grand Unified Models
Junji Hisano, Daiki Kobayashi, Natsumi Nagata
In the supersymmetric grand unified theories (SUSY GUTs), gauge bosons associated with the unified gauge group induce proton decay. We investigate the proton decay rate via the gau…
