Optimal Renormalization Scales and Commensurate Scale Relations
Stanley J. Brodsky, Hung Jung Lu
Commensurate scale relations relate observables to observables and thus are independent of theoretical conventions, such as the choice of intermediate renormalization scheme. The p…
Resolved Photon and Rapidity Gap in Jet Events
Hung Jung Lu
We study the production of jet events containing large rapidity gaps in particle colliders due to the resolved photon mechanism. In particular, we analize these events at DESY HERA…
Precision Tests of Quantum Chromodynamics and the Standard Model
Stanley J. Brodsky, Hung Jung Lu
We discuss three topics relevant to testing the Standard Model to high precision: commensurate scale relations, which relate observables to each other in pertubation theory without…
On the Self-Consistency of Scale-Setting Methods
Stanley J. Brodsky, Hung Jung Lu
We discuss various self-consistency conditions for scale-setting methods. We show that the widely used Principle of Minimum Sensitivity (PMS) is disfavored since it does not satisf…
