Universally Leptophilic Dark Matter From Non-Abelian Discrete Symmetry
Naoyuki Haba, Yuji Kajiyama, Shigeki Matsumoto +2
The positron anomaly recently reported by the cosmic-ray measurements can be explained by the decaying dark matter scenario, where it decays mainly into leptons with the lifetime o…
Extra dimensions and Seesaw Neutrinos at the International Linear Collider
Tomoyuki Saito, Masaki Asano, Keisuke Fujii +6
We study the capability of the international linear collider (ILC) to probe extra dimensions via the seesaw mechanism. In the scenario we study, heavy Kaluza-Klein neutrinos genera…
Seesaw in the bulk
Atsushi Watanabe, Koichi Yoshioka
A five-dimensional seesaw framework is analyzed with the lepton-number-violating propagator of bulk right-handed neutrinos. That can bypass summing up the effects of heavy Majorana…
Deep Correlation Between Cosmic-Ray Anomaly and Neutrino Masses
Shigeki Matsumoto, Koichi Yoshioka
The positron anomaly recently reported by the cosmic-ray measurements suggests that, if explained by the decay of dark matter particle, the decay source is closely linked up with t…
Seesaw Neutrino Signals at the Large Hadron Collider
Shigeki Matsumoto, Takehiro Nabeshima, Koichi Yoshioka
We discuss the scenario with gauge singlet fermions (right-handed neutrinos) accessible at the energy of the Large Hadron Collider. The singlet fermions generate tiny neutrino mass…
