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…
Multiboson Signatures of Doubly Charged Scalars at a Same-Sign Muon Collider
Mariana Frank, Benjamin Fuks, Chayan Majumdar +1
We investigate the sensitivity of a same-sign collider to doubly charged scalars in the Type-II seesaw framework, focusing on the regime in which the doubly charged scalar…
Radiative Dirac neutrino masses and dark matter in a extended model
Chayan Majumdar, Utkarsh Patel, Supriya Senapati +1
We study a extension of the Standard Model (SM) in which Dirac neutrino masses are generated radiatively at the one-loop level through the exchange of new beyond the S…
Probing Dark Sector Particles Coupling to Neutrinos with Double Beta Decay
Noor-Ines Boudjema, Frank F. Deppisch, Antonio Herrero-Brocal +2
Motivated by the observation of non-zero neutrino masses and the potential for discovering physics beyond the Standard Model, numerous experiments are actively searching for neutri…
Exploring two component doublet dark matter
Mariana Frank, Purusottam Ghosh, Chayan Majumdar +1
We propose a two-component dark matter (DM) scenario by extending the Standard Model with two additional doublets, one scalar, and another fermion. To ensure the stabilit…
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…
Relaxing Limits from Big Bang Nucleosynthesis on Heavy Neutral Leptons with Axion-like Particles
Frank F. Deppisch, Tomás E. Gonzalo, Chayan Majumdar +1
Heavy neutral leptons (HNLs) are constrained by requirements of Big Bang Nucleosynthesis (BBN) as their decays significantly impact the formation of the primordial elements. We pro…
Leptonic probes of Alternative Left-Right Symmetric Models
Mariana Frank, Benjamin Fuks, Sumit K. Garg +3
We explore constraints on the parameter space of the alternative left-right model originating from the leptonic sector. Our analyses focuses on both lepton-flavour-conserving obser…
Neutrinoless Double Beta Decay from Scalar Leptoquarks: Interplay with Neutrino Mass and Flavor Physics
P. S. Bhupal Dev, Srubabati Goswami, Chayan Majumdar +1
We perform a comprehensive analysis of neutrinoless double beta decay and its interplay with low-energy flavor observables in a radiative neutrino mass model with scalar leptoquark…
Collider Signatures of boson in the Alternative Left-Right Model
Mariana Frank, Chayan Majumdar, Poulose Poulose +2
Alternative Left-Right Models offer an attractive option to left-right models. Emerging from grand unification, these models are consistent with light scalars which do not in…
Dark Matter in the Alternative Left Right Model
Mariana Frank, Chayan Majumdar, Poulose Poulose +2
The Alternative Left-Right Model is an attractive variation of the usual Left-Right Symmetric Model because it avoids flavour-changing neutral currents, thus allowing the additiona…

Chayan Majumdar, Supriya Senapati, S. Uma Sankar +1
We consider an extended left-right symmetric gauge theory where the neutrino masses are generated through inverse seesaw mechanism. In this model the muon …
