Archimedean Seesaw: Small Neutrino Masses and Large Lepton-number Violation
Tao Han, Alejandro Ibarra, Subhojit Roy +1
Contrary to the common lore that observable lepton-number violation (LNV) is inevitably suppressed by tiny neutrino masses, we identify a class of seesaw models in which arbitraril…

Heavy Neutral Lepton at Same-Sign Muon Collider
Ryuichiro Kitano, Ian Low, Ryutaro Matsudo +2
We explore the discovery potential of heavy neutral leptons (HNLs), motivated by models addressing the origin of neutrino masses, at the proposed high-energy same-sign muon collide…
