Sterile neutrino dark matter in a U(1) extension of the standard model
Károly Seller
We explore the possibilities of dark matter production in a U(1) extension of the standard model, also called the super-weak model. The freeze-in and freeze-out mechanisms are desc…
New physics searches at the ILC positron and electron beam dumps
Kento Asai, Sho Iwamoto, Yasuhito Sakaki +1
We study capability of the ILC beam dump experiment to search for new physics, comparing the performance of the electron and positron beam dumps. The dark photon, axion-like partic…
One-loop corrections to light neutrino masses in gauged U(1) extensions of the standard model
Sho Iwamoto, Timo J. Kärkkäinen, Zoltán Péli +1
We consider gauged U(1) extensions of the standard model of particle physics with three right-handed sterile neutrinos and a singlet scalar. The neutrinos obtain mass via the type…
Wino-Higgsino dark matter in the MSSM from the anomaly
Sho Iwamoto, Tsutomu T. Yanagida, Norimi Yokozaki
In this letter, we show that the wino-Higgsino dark matter (DM) is detectable in near future DM direct detection experiments for almost all consistent parameter space in the sponta…
Sterile neutrino dark matter in a U(1) extension of the standard model
Sho Iwamoto, Károly Seller, Zoltán Trócsányi
We explore the parameter space of a U(1) extension of the standard model -- also called the super-weak model -- from the point of view of explaining the observed dark matter energy…
Supersymmetric Interpretation of the Muon Anomaly
Motoi Endo, Koichi Hamaguchi, Sho Iwamoto +1
The Fermilab Muon collaboration recently announced the first result of measurement of the muon anomalous magnetic moment (), which confirmed the previous result at the B…
