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-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…
IPPOG: a global network for particle physics outreach and education
IPPOG Collaboration
We present the International Particle Physics Outreach Group (IPPOG), a global network dedi- cated to connecting students, educators, and the general public with the world of parti…
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…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-MartÃnez +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…
