17. Exotic Higgs Decays (theory, various models)

Exotic Higgs decays may be our main window to new physics. They are common and often well-motivated in various new physics scenarios, partly due to the small natural width of the Higgs. Some exotic decay modes are cascades resulting in high multiplicity of the final state, and are therefore potentially spectacular. Still, they could easily be missed, partly due to triggering...

18. Higgs decays to exotic particles at CMS

The results of searches for invisible decays of the Higgs boson in the vector boson fusion and associated ZH production modes, where Z decays to a pair of charged leptons or a bbbar quark pair, are presented. Searches performed using data collected in proton-proton collisions at center-of-mass energies of 7 TeV and 8 TeV by the CMS experiment at the LHC. With no excess of the observed data...

19. Higgs decays to exotic particles at ATLAS

The discovery of a Higgs-like particle in ATLAS and CMS at the Large Hadron Collider opened a rich and interesting range of opportunities for discovery of exotic decays, i.e. decays that involve new light states beyond the SM. A large class of simplified and complete models gives rise to peculiar patterns of exotic decays of the Higgs boson, patterns that the ATLAS experiment is exploring...

20. Charged Higgs probes of dark bosons

We suggest top quark decays as a venue to search for light dark force carriers. The top quark is the heaviest particle in the standard model whose decays are relatively poorly measured, allowing sufficient room for exotic decay modes from new physics. A very light (GeV scale) dark gauge boson (Z') is a recently highlighted hypothetical particle that can address some astrophysical anomalies as...
