Investigating the leptonic couplings of doubly charged scalars at the muon collider

Nivedita Ghosh, Santosh Kumar Rai, Tousik Samui +1

We study the lepton flavour conserving and violating couplings of a doubly charged scalar at a 3 TeV muon collider. Using a model independent Lagrangian, we analyse the electron el…

Chasing Long-Lived Doubly Charged Scalars at Future Lepton Colliders

Nandini Das, Dilip Kumar Ghosh, Nivedita Ghosh +1

We come up with a novel search strategy for long-lived doubly charged scalars at future proposed lepton colliders. The doubly charged scalar studied in this work belongs to an $SU(…

Unveiling the CP-odd Higgs in a Generalized 2HDM at a Muon Collider

Nandini Das, Nivedita Ghosh

We revisit the generalized two-Higgs-doublet model (2HDM) with a minimally perturbed lepton specific (Type-X) Yukawa sector in context of the muon collider. The model offers a larg…

Light long-lived particles at the FCC-hh with the proposal for a dedicated forward detector FOREHUNT and a transverse detector DELIGHT

Biplob Bhattacherjee, Herbi K. Dreiner, Nivedita Ghosh +3

In this paper, we propose a dedicated forward detector, FOREHUNT (FORward~Experiment~for~HUNdred~TeV), for 100 TeV FCC-hh for the detection of light long-lived particles (LLP) comi…

Search For a Leptoquark and Vector-like Lepton in a Muon Collider

Nivedita Ghosh, Santosh Kumar Rai, Tousik Samui

The proposal for a high-energy muon collider offers many opportunities in the search for physics beyond the Standard Model (BSM). The collider by construction is likely to be more…
