  Boosted Tops at the LHC

  Cecilia E. Gerber
  University of Illinois - Chicago

  Many physics models of electroweak symmetry breaking and solutions to the
hierarchy problem predict the existence of heavy particles with decay
products that include jets. If these new particles are boosted relative to
their mass, the resulting decay products can fall within a single jet. In
this talk I will describe how the CMS experiment is using information about
the substructure of jets to perform a model-independent search for the
production of a massive, narrow-width, neutral boson decaying into top
quark pairs in 7 TeV pp collisions at the LHC.
