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 scal…
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…
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…
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…
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…
