摘要:The standard lore says that the only observables that are calculable within perturbation theory
in QCD or any gauge theory are those that are infrared and collinear safe. Recently, we have
discovered observables that are not infrared and collinear safe, yet are calculable in perturbation
theory when all orders effects are included. We refer to these observables as Sudakov safe and
unlike infrared and collinear safe observables, their distributions have non-analytic dependence
on the coupling. In this talk, I will discuss one Sudakov safe observable which exhibits independence
on the coupling and manifests the universal collinear splitting functions.
