Findings
Full mass range analysis from 1 GeV to 1 TeV for the second Higgs boson.
Benchmark scenarios for LHC Run 2 searches.
Electroweak corrections to H to hh decay width.
Abstract
We discuss the current status of theoretical and experimental constraints on the real Higgs singlet extension of the Standard Model. For the second neutral (non-standard) Higgs boson the full mass range from 1 GeV to 1 TeV accessible at past and current collider experiments is considered. We present benchmark scenarios for searches for an additional Higgs state in the real Higgs singlet extension of the Standard Model in Run 2 of the LHC. We furthermore discuss electroweak corrections to the H to hh partial decay width within this model.
