Abstract：
The generalized Crewther relation relates the cross section ratio R=σ(e⁺e^－→hadrons)/σ(e⁺e^－→μ⁺μ^－) in e⁺e^－ annihilation with the Bjorken sum rule or the Gross-Llewellyn 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 measmed at the upgrated Beijing Electal 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.
