Jet Observables in Theory and Reality
Davison E. Soper
TL;DR
This paper explores the theoretical and practical aspects of jet observables, focusing on the inclusive jet cross section, the importance of infrared safety, and the impact of power corrections at lower transverse energies.
Contribution
It provides an analysis of the infrared safety and cone definitions in jet measurements and estimates the significance of power corrections at small E_T values.
Findings
Infrared safety is crucial for reliable jet measurements.
Power corrections become significant at lower E_T.
Cone definitions impact the jet cross section analysis.
Abstract
I discuss the one jet inclusive jet cross section, d sigma /dE_T emphasizing the concept of infrared safety and the cone definition of jets. Then I estimate the size of power corrections to the jet cross section, which become important at smaller values of E_T.
