Vacuum structure of the ℤ2 symmetric Georgi-Machacek model
Abstract We discuss the vacuum structure of a version of the Georgi-Machecek model with an exact ℤ2 symmetry acting on the triplet fields. Besides the usual custodial-symmetric model, with ρ = 1 at tree-level, a model with a dark matter candidate is also viable. The other phases of the model lead to...
