Hadronic Probes of Non-Standard Neutrino Interactions
Carlos Henrique de Lima, David McKeen, John Ng +1
In this work, we study leptonic decays of hadrons as probes of light neutrinophilic scalars that mediate enhanced neutrino self-interactions. Such scalars can be emitted in process…

Probing Lepton Number Violation at Same-Sign Lepton Colliders
Carlos Henrique de Lima, David McKeen, John N. Ng +2
Same-sign lepton colliders offer a promising environment to probe lepton number violation. We study processes that change lepton number by two units in the context of Majorana heav…

Signatures of Bulk Neutrinos in the Early Universe
David McKeen, John Ng, Michael Shamma
Neutrino masses and quantum gravity are strong reasons to extend the standard model of particle physics. A large extra dimension can be motivated by quantum gravity and can explain…
