TL;DR

This paper explores advanced jet analysis techniques at a 100 TeV collider, including recoil-free axes, scale-invariant grooming, and a robust jet calibration method, enhancing precision in high-energy physics experiments.

Contribution

It introduces new jet (sub)structure methods such as recoil-free axes and a novel calibration observable, improving jet analysis robustness at future colliders.

Findings

Recoil-free jet axis is robust against pileup.

Soft drop declustering respects QCD scale invariance.

A new jet calibration method is insensitive to jet flavor and scale.

Abstract

We present three case studies at a 100 TeV proton collider for how jet analyses can be improved using new jet (sub)structure techniques. First, we use the winner-take-all recombination scheme to define a recoil-free jet axis that is robust against pileup. Second, we show that soft drop declustering is an effective jet grooming procedure that respects the approximate scale invariance of QCD. Finally, we highlight a potential standard candle for jet calibration using the soft-dropped energy loss. This latter observable is remarkably insensitive to the scale and flavor of the jet, a feature that arises because it is infrared/collinear unsafe, but Sudakov safe.
