Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Stau study at the ILC and its implication for the muon g-2 anomaly
Motoi Endo, Koichi Hamaguchi, Sho Iwamoto +4
Once all the sleptons as well as the Bino are observed at the ILC, the Bino contribution to the muon anomalous magnetic dipole moment (muon ) in supersymmetric (SUSY) models c…
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…
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…
