Hadronization effects in event shape moments

Abstract

We study the moments of hadronic event shapes in e + e ‐ annihilation within the context of next-to-next-to-leading order (NNLO) perturbative QCD predictions combined with non-perturbative power corrections in the dispersive model. This model is extended to match the NNLO perturbative prediction. The resulting theoretical expression has been compared to… (More)
