Natural Seesaw and Leptogenesis from Hybrid of High-Scale Type I and TeV-Scale Inverse
Kaustubh Agashe, Peizhi Du, Majid Ekhterachian +3
We develop an extension of the basic inverse seesaw model which addresses simultaneously two of its drawbacks, namely, the lack of explanation of the tiny Majorana mass term fo…
Electroweak Baryogenesis above the Electroweak Scale
Alfredo Glioti, Riccardo Rattazzi, Luca Vecchi
Conventional scenarios of electroweak (EW) baryogenesis are strongly constrained by experimental searches for CP violation beyond the SM. We propose an alternative scenario where t…
The Bearable Compositeness of Leptons
Michele Frigerio, Marco Nardecchia, Javi Serra +1
Partial compositeness as a theory of flavor in the lepton sector is assessed. We begin presenting the first systematic analysis of neutrino mass generation in this context, and ide…
Hybrid seesaw leptogenesis and TeV singlets
Kaustubh Agashe, Peizhi Du, Majid Ekhterachian +3
The appealing feature of inverse seesaw models is that the Standard Model (SM) neutrino mass emerges from the exchange of TeV scale singlets with sizable Yukawa couplings, which ca…
Neutrino Oscillations in Dark Backgrounds
Francesco Capozzi, Ian M. Shoemaker, Luca Vecchi
We examine scenarios in which a dark sector (dark matter, dark radiation, or dark energy) couples to the active neutrinos. For light and weakly-coupled exotic sectors we find that…
