A priority based noise tolerant jet framework and algorithm

TL;DR

This paper presents a new p-jet framework that improves jet reconstruction by reducing background pileup contamination while maintaining computational speed, demonstrated through comparison with existing algorithms.

Contribution

The paper introduces the p-jet framework, a novel jet definition method that is both fast and more resistant to pileup effects compared to traditional algorithms.

Findings

p-jets match the speed of anti-k_T algorithms

p-jets better suppress pileup contamination

Effective in reconstructing low energy jets from Z boson events

Abstract

We introduce a new framework for jet definitions called p-jets that matches the computational speed of the currently used anti-k_T jet algorithm, but avoids combining much of the energy from background pileup events with signal jets. As a first illustration of the p-jet framework, we compare the effectiveness of a p-jet algorithm to the anti-k_T algorithm in reconstructing low energy jets from resonant Z boson production and 50 pileup events.
