Dark Matter and Collider Searches in -Symmetric 2HDM with Vector Like Leptons
Indrani Chakraborty, Dilip Kumar Ghosh, Nivedita Ghosh +1
We study the -symmetric two Higgs doublet model by adding two generations of vector like leptons (VLL) which are odd under a discrete symmetry. The lightest neutral comp…
Revisiting Generalized Two Higgs Doublet Model in the Light of Muon Anomaly and Lepton Flavor Violating Decays at HL-LHC
Nivedita Ghosh, Jayita Lahiri
One of the main motivations to look beyond the SM is the discrepancy between the theoretical prediction and observation of anomalous magnetic moment of muon. Alleviating this tensi…
Associated production in the flavorful scenario for
Siddharth Dwivedi, Adam Falkowski, Dilip Kumar Ghosh +1
The flavorful model with its couplings restricted to the left-handed second generation leptons and third generation quarks can potentially resolve the observed anomalies…
Charged Higgs searches in the Georgi-Machacek model at the LHC
Nivedita Ghosh, Swagata Ghosh, Ipsita Saha
The Georgi-Machacek Model allows for a large triplet vacuum expectation value (vev) with a custodial symmetric scalar potential. This manifestly leads to large charged Higgs coupli…
Collider signature of Leptoquark and constraints from observables
Aritra Biswas, Dilip Kumar Ghosh, Nivedita Ghosh +2
One of the most popular models that is known to be able to solve the lepton flavour universality violating charged () and neutral current () anomalies is the Leptoq…
Distinctive Collider Signals for a Two Higgs Triplet Model
Dilip Kumar Ghosh, Nivedita Ghosh, Biswarup Mukhopadhyaya
The extension of the Standard Model (SM) with two complex scalar triplets enables one to have the Type II seesaw mechanism operative consistently with texture-zero neut…
