New-𝝂 Physics: From Colliders to Cosmology

9 Apr 2025, 15:00 → 11 Apr 2025, 17:00 Europe/London

D110 (Dawson Building)

Chris Hays (Oxford), Chris Pollard (Glasgow), Michael Spannowsky (IPPP, Durham University), Rodrigo Alonso (Durham)

The workshop brings together various particle physics communities to review experimental searches for new neutrinos.  The workshop aims to extend benchmark interpretations to be applied across collider and non-collider experiments, and to identify any gaps in existing searches and interpretations.  Particular focus will be on new neutrinos at relatively low mass, accessible through decays of known particles, but will also include the potential for finding evidence for new neutrinos at high mass.
