High precision test of QCD at Beijing Electron Positron Collider
Description
The generalized Crewther relation relates the cross section ratio Rσ (e+e-→hadrons)/σ(e+e-→μ+μ-) in e+e- annihilation with the Bjorken sum rule or the Gross-Liewellyn Smith sum rule in deep inelastic scattering and provides a fundamental connection for observables in Quantum Chromodynamics (QCD) without scale or scheme ambiguities. The ratio R can be measured at the up grated Beijing electron Positron Collider or the τ-Charm factory with higher precision and thus can be served for a high precision test of QCD in the standard model
