Exploring Higgs Triplet Models - Georgi-Machacek Model’s Unique Dynamics — •Saurav Bania1, Sara Chopra1, Gudrid Moortgart-Pick1, and Sven Heinemeyer2 — 1Universität Hamburg — 2Consejo Superior de Investigaciones Científicas (CSIC)
In our research, we investigate the sum rules within a Higgs Triplet Model (the Georgi-Machacek (GM) Model). This model contains neutral, singly charged and doubly charged Higgs Boson. We analyse the couplings obtained from the Triplet Lagrangian and extract possible sum rules out of them where the doubly charged Higgs bosons lead to relevant changes w.r.t models that contain only Higgs singlets and doublets. We also test whether the custodial symmetry is preserved.
We investigate the High-Energy Vector-Boson and Fermion scatterings and test whether the E2 and E4 dependencies cancel out, i.e. unitarity is preserved in the GM model. We also obtain the mass bounds that arise from the constraints and specifically focus on the doubly-charged Higgs (H5++) that lead to the alteration of unitarity sum rules compared to the models with Higgs singlets and doublets.
