Hadronic antenna patterns to distinguish production mechanisms for large-E T jets

Hadronic antenna patterns provide a tool able to diagnose different patterns of colour flow in large-E _T jet events. They reflect the underlying short-distance dynamics, and are sensitive to colour coherence and interference between the initial- and final-state partons. We discuss how hadronic antenna patterns may be used on large-E _T events from the Fermilab Tevatron or the CERN LHC to distinguish between conventional QCD and new physics production mechanisms such as a possible Z′ boson or compositeness.
