Analysis of up to Next-to-Next-to-Leading Order QCD Corrections
Wen-Yuan Li, Ting Sun, Sheng-Quan Wang +4
The rare exclusive decay of the Higgs boson is an important channel for measuring the Yukawa coupling of the charm quark. In this article, we analyze the process by…
Renormalisation
Leonardo Di Giustino
We give an introduction to renormalisation, focusing first on a pedagogical description of fundamental concepts of the procedure and its features, then we introduce the renormalisa…
Scheme-independent determination of the QCD running coupling at all scales from jet observables using the principle of maximum conformality and infinite-order scale setting
Leonardo Di Giustino, Stanley J. Brodsky, Philip G. Ratcliffe +2
We present a new approach to determining the strong coupling , over the entire range of validity of perturbative QCD, for scales above and up to the Plan…
The Principle of Maximum Conformality Correctly Resolves the Renormalization-Scheme-Dependence Problem
Jiang Yan, Stanley J. Brodsky, Leonardo Di Giustino +3
In this paper, we clarify a serious misinterpretation and consequent misuse of the Principle of Maximum Conformality (PMC), which also can be served as a mini review of PMC. We emp…
Elimination of QCD Renormalization Scale and Scheme Ambiguities
Leonardo Di Giustino, Stanley J. Brodsky, Philip G. Ratcliffe +2
We present results for the thrust distribution in the electron positron annihilation to the three jet process at NNLO in the perturbative conformal window of QCD, as a function of…
