Scale Breaking in Inclusive Charged Particle Production by $e^+ e^-$ Annihilation

The scale cross section s d σ d x p for inclusive charged-particle production in e + e − annihilation has been studied for c.m. energies W between 12.0 and 36.7 GeV. Scale breaking is observed. For x p >0.2 the cross section decreases by ≈20% when W increases from 14 to 35 GeV. The production angular distribution was used to separate the longitudinal and transverse cross-section contributions and to determine the ratio of the structure functions m W 1 and v W 2 .
