Abstract of Hewett's Wednesday, 4/2/14 night talk, “Higgs: The Theory, The
Discovery, and the Fate of the Universe”:  The discovery of a Higgs boson is a
spectacular triumph! The existence of the Higgs was first theorized in 1964 as a
means to generate mass for fundamental particles.  After an intense particle-hunt,
its discovery fills the last missing piece of the Standard Model of particle
physics. Hewett will explain the workings of the Higgs mechanism, review the
decades-long quest for the elusive particle, describe how it was eventually
detected, and discuss what comes next and how it is tied to the fate of the

Abstract of Hewett's Thursday, 4/3/14 afternoon talk, "The LHC Confronts
Supersymmetry": The Large Hadron Collider is providing our first clear view of the
Terascale and is confronting our most cherished theories with data, in particular
Supersymmetry.  Supersymmetry arises from a symmetry allowed by nature that is
simply an extension of the familiar translations, rotations, and boosts.
Supersymmetry at the Terascale offers attractive solutions to many outstanding
questions, including the weak hierarchy problem, the dark matter puzzle, and grand
unification of the forces. Supersymmetry at the Terascale offers testable
predictions that differ between models.  So far, LHC searches for Supersymmetry have
come up short and the newly discovered Higgs-like boson is surprisingly difficult to
accommodate within the simplest Supersymmetry models. I will review the implications
of this data and, in particular, I will show that a region of parameter space within
the phenomenological Minimal Supersymmetric Standard Model can easily evade the LHC
searches and accommodate a 125 GeV Higgs boson, while resulting in acceptable values
of fine-tuning.
