Abstract(s)

The recently discovered resonance at 125 GeV shows properties, so far, consistent with the Stan- dard Model Higgs boson. It is, nonetheless, important to directly search the full mass range avail- able at the Large Hadron Collider (LHC). Searches for a high-mass Higgs boson, with SM-like properties, can be performed without placing any bias on the nature of the new particle. Moreover, they can be used as a starting point for Beyond the Standard Model scenarios, that can be stud- ied by simply rescaling the Standard Model analyses. The latest results from ATLAS and CMS, using data from the LHC to search for SM-like Higgs bosons with masses substantially above the observed 125 GeV Higgs boson, are presented. These include ZZ and WW decay modes and explore the 200 GeV to 1 TeV mass range, where no significant excesses have been observed.
