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…

LHC Signatures of Neutral Scalar Cascades in the symmetric 3HDM

Baradhwaj Coleppa, Akshat Khanna, Santosh Kumar Rai +1

Extending the scalar sector is one of the standard approaches to exploring scenarios beyond the Standard Model. In this work, we examine the collider phenomenology of the Three Hig…

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…

Exploring Fermionic Dark Matter in the Presence of Scalar Leptoquarks

Shyamashish Dey, Santosh Kumar Rai

We study an extension of the vector-like lepton dark matter model by introducing scalar leptoquarks that modify the properties of the vector-like lepton dark matter candidate, help…

Constraining the 3HDM Parameter Space using Active Learning

Nipun Batra, Baradhwaj Coleppa, Akshat Khanna +2

One of the standard ways to study scenarios beyond the Standard Model involves extending the Higgs Sector. This work examines the Three Higgs Doublet Model (3HDM) in a Type-Z or de…

Tracing Neutrino Non-Standard Interactions through Charged Lepton Collisions

Sudip Jana, Saumyen Kundu, Santosh Kumar Rai

Neutrino non-standard interactions (NSI) play a crucial role in neutrino oscillations and can provide valuable insights for constructing models of neutrino masses and mixing. While…
