Description

The $SU(2{)}_L$ triplet scalar extension of the Standard Model offers‬ interesting collider phenomenology. The minimal extension with custodial symmetry demands one real triplet scalar with a hypercharge‬ ‭quantum number zero, and one complex triplet scalar with a hypercharge ‬quantum number one, in addition to the Standard Model Higgs doublet. This model is dubbed as extended Georgi-Machacek (eGM) model. In this presentation, I will‬ discuss the theoretical bounds on the model parameter space, such as next-to-leading‬ order unitarity and state-of-the-art bounded from below conditions on the potential. I will‬ present the maximal mass splitting among the exotic Higgs bosons in the eGM model from the Bayesian fit‬ with Markov Chain Monte Carlo simulations. Finally, I will discuss the possibility of studying new decay modes in the eGM model,‬ that could potentially be observed at the LHC and other future colliders.
