Large mass splittings for fourth generation fermions allowed by LHC Higgs boson exclusion
Large mass splittings for fourth generation fermions allowed by LHC Higgs boson exclusion
In the context of the standard model with a fourth generation, we explore the allowed mass spectra in the fourth-generation quark and lepton sectors as functions of the Higgs mass. Using the constraints from unitarity and oblique parameters, we show that a heavy Higgs allows large mass splittings in these …
