ConclusionsThe experimental particle physics group

Is pursuing exciting frontier physics @ CERN Is hyper-active Is engaged in next gen electronics R&D Is cohesive and supportive Is establishing an experimental astrophysics

program using the LSST telescope Is looking for a few good students to

continue our successes

What is the Higgs Bosonand Have We Discovered It

Yet?

21

Hot Off the Press ResultsWe definitely know where the Higgs is

NOT hidingAnd we have a hint (only) as to where it

may be found
