Fate of Metastable Vacua in the Type-II Two-Higgs Doublet Model
Debtosh Chowdhury, Kirtimaan A. Mohan, Poulami Mondal +1
The scalar potential of the Two-Higgs-Doublet Model (2HDM) can admit multiple non-degenerate vacua due to the presence of the two Higgs doublets unlike the Standard Model (SM). For…
One-loop renormalization and parameter in the Georgi-Machacek model
Debtosh Chowdhury, Anirban Kundu, Poulami Mondal +2
We study the one-loop renormalization of the Georgi-Machacek model. At one loop, the renormalization of the model is phenomenologically important when triggered by operators that a…
Light Scalars in the Extended Georgi-Machacek Model
Poulami Mondal, Subrata Samanta
We perform global fits of the CP-conserving Georgi-Machacek (GM) and extended Georgi-Machacek (eGM) models, incorporating a light CP-even beyond the Standard Model (BSM) scalar wit…
Next-to-Leading Order Unitarity Fits in the Extended Georgi-Machacek Model
Debtosh Chowdhury, Poulami Mondal, Subrata Samanta
The Georgi-Machacek (GM) model is a triplet scalar extension of the Standard Model (SM) that preserves custodial symmetry (CS) due to an explicit global sy…
