Constraining the SMEFT Extended with Sterile Neutrinos at FCC-ee
Patrick D. Bolton, Frank F. Deppisch, Suchita Kulkarni +2
We investigate how extensions of the Standard Model (SM) involving heavy neutral leptons (HNLs) can be probed at FCC-ee, the proposed high-energy circular collider. Using…
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…
Hadron Collider Signatures of Lepton Number Violation in the Type II Seesaw Model
Patrick D. Bolton, Jonathan Kriewald, Miha Nemevšek +2
We examine the prospect of observing genuine lepton number violating (LNV) signals at hadron colliders in the context of the Type II seesaw mechanism. The model features smoking gu…
Probing the Nature of Heavy Neutral Leptons in Direct Searches and Neutrinoless Double Beta Decay
Patrick D. Bolton, Frank F. Deppisch, Mudit Rai +1
Heavy Neutral Leptons (HNLs) are a popular extension of the Standard Model to explain the lightness of neutrino masses and the matter-antimatter asymmetry through leptogenesis. Fut…
