Displaced Signals from Long-lived Particles in Neutrinoless Double Beta Decay

Patrick D. Bolton, Noor-Inès Boudjema, Frank F. Deppisch +2

Much of the literature on neutrinoless double beta () decay with light new-physics mediators focuses on invisible missing energy. We investigate the scenario in which a massi…

Probing SMEFT at Belle II with displaced dilepton vertices

Patrick D. Bolton, Fabian Esser, Lukáš Gráf +3

The existence of right-handed (RH) neutrinos is strongly motivated by the observation of small neutrino masses and as a means to shed light on the origin of parity violation in the…

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…

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…

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 Heavy Neutrino Magnetic Moments at the LHC using Long-Lived Particle Searches

Rebeca Beltrán, Patrick D. Bolton, Frank F. Deppisch +2

We explore long-lived particle (LLP) searches using non-pointing photons at the LHC as a probe for sterile-to-sterile and active-to-sterile transition magnetic dipole moments of st…

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…

Probes of Heavy Sterile Neutrinos

Patrick D. Bolton, Frank F. Deppisch, P. S. Bhupal Dev

We review probes of heavy sterile neutrinos, focusing on direct experimental searches and neutrinoless double beta decay. Working in a phenomenological parametrization, we emphasiz…

Measurements of Decay with Polarised Muons as a Probe of New Physics

P. D. Bolton, S. T. Petcov

Working within the Standard Model effective field theory approach, we examine the possibility to test charged lepton flavour violating (cLFV) new physics (NP) by angular measuremen…

A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics

J. Aalbers, K. Abe, V. Aerne +591

The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leadi…

Neutrinoless Double Beta Decay via Light Neutralinos in R-Parity Violating Supersymmetry

Patrick D. Bolton, Frank F. Deppisch, P. S. Bhupal Dev

We perform a study of neutrinoless double beta () decay mediated by the lightest neutralino of arbitrary mass in the Minimal Supersymmetric Standard Model (MSSM) under the pr…

Probing Active-Sterile Neutrino Transition Magnetic Moments with Photon Emission from CENS

Patrick D. Bolton, Frank F. Deppisch, Kåre Fridell +3

In the presence of transition magnetic moments between active and sterile neutrinos, the search for a Primakoff upscattering process at coherent elastic neutrino-nucleus scattering…

Two-Neutrino Double Beta Decay with Sterile Neutrinos

Patrick D. Bolton, Frank F. Deppisch, Lukáš Gráf +1

Usually considered a background for experimental searches for the hypothetical neutrinoless double beta decay process, two-neutrino double beta decay nevertheless provides a comple…

Probing New Physics with Long-Range Neutrino Interactions: An Effective Field Theory Approach

Patrick D. Bolton, Frank F. Deppisch, Chandan Hati

We investigate forces induced by the exchange of two light neutrinos between Standard Model (SM) fermions in the presence of effective operators parametrising physics beyond the SM…

Neutrinoless double beta decay versus other probes of heavy sterile neutrinos

Patrick D. Bolton, Frank F. Deppisch, P. S. Bhupal Dev

We make a comparative study of the neutrinoless double beta decay constraints on heavy sterile neutrinos versus other direct and indirect constraints from both lepton number conser…

Alternative formulation of left-right symmetry with conservation and purely Dirac neutrinos

Patrick D. Bolton, Frank F. Deppisch, Chandan Hati +2

We propose an alternative formulation of a Left-Right Symmetric Model (LRSM) where the difference between baryon number () and lepton number () remains an unbroken symmetry.…
