Title:   Subjet structure as a new search channel at the LHC

Abstract:
A feature of LHC physics above the electroweak symmetry-breaking scale is that 
particles with masses around this scale (e.g. W,Z,H,top) can be produced well 
above threshold. This means that in many important processes they have a 
considerable boost, and if they decay to hadrons, these hadrons appear in 
a single jet. Analysing the substructure of this jet is a powerful method 
for identifying such events. I describe the techniques and their application, 
especially in WW scattering and in low mass Higgs->bb searches
