The corrections are sizeable for all variables, however their magnitude is substantially different for different observables. We observe that inclusion of the NNLO corrections yields a considerably better agreement between theory and experimental data both in shape and normalisation of the event shape distributions.6 pages, contribution to the Proceedings of RADCOR07, FlorenceHigh Energy Physics - Phenomenologytext
