SUMMARY:Searching for new physics at the LHC: The story you haven't he
 ard\, Physics Department Colloquium\, Michael Williams \, MIT
DESCRIPTION:There are two ways to discover new particles: we can make 
 them in the lab and observe their decays or we can observe discrepanci
 es between precision measurements and theoretical predictions.  Both m
 ethods are being employed by the LHCb experiment at CERN to search for
  what lies beyond the Standard Model (SM) of particle physics.   The L
 HCb experiment has published over 170 papers since 2011.  The core phy
 sics program involves making precise measurements of observables whose
  SM predictions are well known and that are expected to be extremely s
 ensitive to a wide range of beyond the SM theories\, e.g.\, supersymme
 try.  The magic of quantum mechanics permits particles that are too ma
 ssive to be produced in the lab\, even at the LHC\, to make significan
 t contributions to the observables measured at LHCb.   If\, in fact\, 
 the lightest new particles cannot be produced directly at the LHC\, th
 en our only hope for discovery at a collider in the coming decades is 
 via such indirect observations.  I will also discuss direct searches f
 or light dark matter candidates and other future prospects for discove
 ry.
