Description
Summary:Power corrections to hadronic event shapes are estimated using a recently suggested relationship between perturbative and non-perturbative effects in QCD. The infrared cutoff dependence of perturbative calculations is related to non-perturbative contributions with the same dependence on the energy scale Q. Corrections proportional to 1 Q are predicted, in agreement with experiment. An empirical proportionality between the magnitudes of perturbative and non-perturbative coefficients is noted.
