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(…

Vector Dark Matter in a extended 2HDM
Nandini Das, Juhi Dutta, Dilip Kumar Ghosh +1
We investigate the possibility of having a vector boson dark matter in a extended two-Higgs-doublet model (2HDM) setup. The gauge boson gains mass when a SM singlet comple…

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…
