New Horizons in Jet Substructure and Boosted Physics @ LHC

Jets are outputs of clustering algorithms that group the hadronic
energy cells of detectors in a well-defined way. Understanding and
precisely calculating jet-observables are of immense importance in
verifying and understanding the Standard Model of particle physics and
especially in the discovery of new physics.  In the first half of the
talk, I will briefly review new ideas in jet physics and mention the
remarkable progress made in the last few years.  In the next half, I
will introduce a radically new proposal -- a non-deterministic
clustering algorithm, which renders remarkable stability to jet
observables and provides new measures for discovering new physics.
