New approach for jet-shape identification of TeV-scale particles at the LHC

Understand

A new approach to jet-shape identification based on linear regression is discussed.

• It is designed for searches for new particles at the TeV scale decaying hadronically with strongly collimated jets.
• We illustrate the method using a Monte Carlo simulation for pp collisions at the LHC with the goal to reduce the contribution of QCD-induced events.
• We focus on a rather generic example X to ttbar to hadrons, with X being a heavy particle, but the approach is well suited for reconstruction of other decay channels characterized by a cascade decay of known states.
