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.…
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…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
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…
Completing the one-loop SMEFT Renormalization Group Evolution
Marco Ardu, Xabier Marcano
In this work we consider the Standard Model Effective Field Theory extended with right-handed neutrinos, the SMEFT, and calculate the full set of one-loop anomalous dimensions t…
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…
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…
Interference effects in LNV and LFV semileptonic decays: the Majorana hypothesis
A. Abada, C. Hati, X. Marcano +1
In the case where the Standard Model is extended by one heavy Majorana fermion, the branching fractions of semileptonic meson decays into same-sign and opposite-sign dileptons are…
