TL;DR: The results are compared with the predictions of Monte Carlo models of complete second-order perturbative quantum chromodynamics and fragmentation, and the string fragmentation model provides a satisfactory description of the measured energy-energy correlation cross section, whereas incoherent jet formation does not.

TL;DR: A high-precision measurement of the differential cross section for Bhabha scattering is presented, and effects due to electroweak interference are observed and agree well with the predictions of the Glashow-Salam-Weinberg model.
