Novel analysis for the energy-energy correlation in electron-positron annihilation in the perturbative domain
Zhu-Yu Ren, Sheng-Quan Wang, Jian-Ming Shen +4
The energy-energy correlation (EEC) in electron-positron annihilation plays a crucial role in precision tests of quantum chromodynamics (QCD) and measurements of the QCD coupling c…

A reanalysis of event shape distributions in electron-positron annihilation
Zhu-Yu Ren, Sheng-Quan Wang, Jian-Ming Shen +2
Theoretical calculations for event shape observables are often determined by using the conventional scale setting; i.e. the procedure defined by setting the renormalization scale t…

Self-consistent analysis for the process
Sheng-Quan Wang, Zhu-Yu Ren, Jian-Ming Shen +3
The next-to-next-to-leading-order (NNLO) pQCD predictions for both the decay width and the transition form factor in the process, based on nonrelativistic QC…
