Description

Shower deconstruction is a method to look for new physics in a hadronic environment. It is the first approach of an all-order resummed matrix element method.


By calculating the likelihood if a fatjet looks more like signal or more like background

Signal

Background

it allows to perform an hypothesis test. By specifying where to cut on chi, you can purify your sample and reject QCD backgrounds.
