TL;DR

This paper explores scaling patterns in QCD jet emissions at hadron colliders, deriving theoretical models and proposing experimental tests to validate these patterns in LHC data.

Contribution

It introduces new perturbative QCD-based models for Poisson and staircase scaling in jet emissions, including effects of parton densities, and suggests experimental validation methods.

Findings

Derivation of Poisson and staircase scaling patterns from perturbative QCD

Parton density effects enhance staircase scaling at low multiplicities

Proposed experimental tests in Z+jets and QCD gap jets production

Abstract

Jet emission at hadron colliders follows simple scaling patterns. Based on perturbative QCD we derive Poisson and staircase scaling for final state as well as initial state radiation. Parton density effects enhance staircase scaling at low multiplicities. We propose experimental tests of our theoretical findings in Z+jets and QCD gap jets production based on minor additions to current LHC analyses.
