Neutrino t-channels at Colliders: When Light Neutrinos Matter
Claudia Garcia-Garcia, Manuel González-López, Xabier Marcano +1
Heavy Neutral Lepton (HNL)-mediated t-channel processes provide a unique opportunity to probe mass scales beyond the kinematic reach of direct production at high-energy colliders.…
The Majoron Cosmological Window: Dark Matter and Thermal Leptogenesis
Arturo de Giorgi, Daniel Naredo-Tuero, Xavier Ponce DÃaz
The majoron is the Nambu-Goldstone boson associated with the spontaneous breaking of a global symmetry. Remarkably, the minimal majoron framework can simultaneously address t…
Leptogenesis and Dark Matter in an Inverse Seesaw from gauged B-L breaking
Enrique Fernández-MartÃnez, 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…
Global Lepton Flavour Violating Constraints on New Physics
Enrique Fernández-MartÃnez, Xabier Marcano, Daniel Naredo-Tuero
We perform a global analysis of the bounds from charged lepton flavour violating observables to new physics. We parametrize generic new physics through the Effective Field Theory f…
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,…
Misconceptions in Neutrino Oscillations in presence of a non-Unitary Mixing
Mattias Blennow, Pilar Coloma, Enrique Fernández-MartÃnez +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…
