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 Díaz
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-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…
Improving the Global SMEFT Picture with Bounds on Neutrino NSI
Pilar Coloma, Enrique Fernández-Martínez, Jacobo López-Pavón +3
We analyze how neutrino oscillation and coherent elastic neutrino-nucleus scattering data impact the global SMEFT fit. We first review the mapping between the SMEFT parameters and…
Living at the Edge: A Critical Look at the Cosmological Neutrino Mass Bound
Daniel Naredo-Tuero, Miguel Escudero, Enrique Fernández-Martínez +2
Cosmological neutrino mass bounds are becoming increasingly stringent. The latest limit within CDM from Planck 2018+ACT lensing+DESI is at 95\% CL, v…
New global bounds on heavy neutrino mixing
Daniel Naredo-Tuero
We present an updated and improved global fit analysis of precision and flavor observables so as to derive constraints on deviations from unitarity in the leptonic mixing matrix. W…
Global Lepton Flavour Violating Constraints on New Physics
Enrique Fernández-Martínez, 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…
Bounds on lepton non-unitarity and heavy neutrino mixing
Mattias Blennow, Enrique Fernández-Martínez, Josu Hernández-García +3
We present an updated and improved global fit analysis of current flavor and electroweak precision observables to derive bounds on unitarity deviations of the leptonic mixing matri…
HNL mass degeneracy: implications for low-scale seesaws, LNV at colliders and leptogenesis
Enrique Fernández-Martínez, Xabier Marcano, Daniel Naredo-Tuero
Low-scale seesaw variants protected by lepton number symmetry provide a natural explanation of the smallness of neutrino masses but, unlike their higher-scale counterparts, with po…
