  One item on the agenda of future colliders is certain to be the Higgs boson.
What is it trying to tell us? The primary objective of any future collider must
surely be to identify physics beyond the Standard Model, and supersymmetry is
one of the most studied options. it Is supersymmetry waiting for us and, if so,
can LHC Run 2 find it? The big surprise from the initial 13-TeV LHC data has
been the appearance of a possible signal for a new boson X with a mass ~750
GeV. What are the prospects for future colliders if the X(750) exists? One of
the most intriguing possibilities in electroweak physics would be the discovery
of non-perturbative phenomena. What are the prospects for observing sphalerons
at the LHC or a future collider?
