abstract
We investigate the power-suppressed corrections to the mean values of various quantities that characterise the shapes of final states in deep inelastic lepton scattering. Our method is based on an analysis of one-loop Feynman graphs containing a massive gluon, which is equivalent to the evaluation of leading infrared renormalon contributions. As in $\ee$ annihilation, we find that the leading corrections are proportional to $1/Q$. We give quantitative estimates based on the hypothesis of a universal low-energy effective coupling.

Second-order QCD corrections to event shape distributions in deep inelastic scattering
The NNLO QCD corrections to DIS event shape distributions and their mean values are computed for the first time, reducing scale uncertainties and improving the description of H1 and ZEUS data.
