Abstract
We investigate the effect of introducing a sequential generation of chiral fermions in the Higgs triplet model with nontrivial mixing between the doublet and triplet Higgs. We use the available Large Hadron Collider data for Higgs boson production and decay rates, the constraints on the fourth generation masses, and impose electroweak precision constraints from the S, T and U parameters. Our analysis shows that a standard model (SM)–like Higgs boson state at can be accommodated in the Higgs triplet model with four generations, and thus, that four generations survive collider and electroweak precision constraints in models beyond SM.
