Higgs bosons at 98 and 125 GeV at LEP and the LHC

Journal of High Energy Physics volume 2013, Article number: 69 (2013) Cite this article

Abstract

We discuss NMSSM scenarios in which the lightest Higgs boson h 1 is consistent with the small LEP excess at ~ 98 GeV in e + e − → Zh with \( h\to b\overline{b} \) and the heavier Higgs boson h 2 has the primary features of the LHC Higgs-like signals at 125 GeV, including an enhanced γγ rate. Verification or falsification of the 98 GeV h 1 may be possible at the LHC during the 14 TeV run. The detection of the other NMSSM Higgs bosons at the LHC and future colliders is also discussed, as well as dark matter properties of the scenario under consideration.
