Dynamical grooming of QCD jets
Abstract
We propose a new class of infrared-collinear (IRC) and Sudakov safe observables with an associ-ated jet grooming technique that removes dynamically soft and large angle branches. It is based onidentifying thehardestbranch in the Cambridge/Aachen re-clustering sequence and discarding priorsplittings that occur at larger angles. This leads to a dynamically generated cut-off on the phase spaceof the tagged splitting that is encoded in a Sudakov form factor. In this exploratory study we focus onthe mass and momentum sharing distributions of the tagged splitting which we analyze analyticallyto modified leading logarithmic accuracy and compare to Monte-Carlo simulations
