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…
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…
Vector Boson Fusion Signatures of Superheavy Majorana Neutrinos at Muon Colliders
Parham Dehghani, Mariana Frank, Benjamin Fuks
We investigate the sensitivity of future high-energy muon colliders to heavy Majorana neutrinos, considering both opposite-sign () and same-sign () collision mo…
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…
Stability of the Standard Model Vacuum with Vector-Like Leptons: A Critical Examination
Kivanc Y. Cingiloglu, Mariana Frank
The stability of the Standard Model (SM) Higgs vacuum is a long-standing issue in particle physics. The SM Higgs quartic coupling parameter is expected to become negative at high s…
Collider imprint of vector-like leptons in light of anomalous magnetic moment and neutrino data
Parham Dehghani, Mariana Frank, Benjamin Fuks
We investigate the impact of incorporating vector-like leptons into the Standard Model, aiming to address longstanding puzzles related to the anomalous magnetic moments of the muon…
