Leptogenesis and Dark Matter in an Inverse Seesaw from gauged B-L breaking
Enrique Fernández-Martínez, Ana Luisa Foguel, Xabier Marcano +3
We study a dynamical realization of the low-scale Inverse Seesaw mechanism in which the approximate symmetry is gauged and spontaneously broken. Anomaly cancellation requires…
Cosmogenic neutrinos as probes of new physics
Luighi P. S. Leal, Daniel Naredo-Tuero, Renata Zukanovich Funchal
The scattering of extremely energetic cosmic rays with both cosmic microwave background and extragalactic background light, can produce neutrinos,…
Clash of the Titans: ultra-high energy KM3NeT event versus IceCube data
Shirley Weishi Li, Pedro Machado, Daniel Naredo-Tuero +1
KM3NeT has reported the detection of a remarkably high-energy through-going muon. Lighting up about a third of the detector, this muon likely originated from a neutrino exceeding 1…
Misconceptions in Neutrino Oscillations in presence of a non-Unitary Mixing
Mattias Blennow, Pilar Coloma, Enrique Fernández-Martínez +5
Deviations from unitarity of the CKM matrix in the quark sector are considered excellent windows to probe physics beyond the Standard Model. In its leptonic counterpart, the PMNS m…
