摘要
In this talk I summarize the two-loop analysis of the 1/Q power corrections to jet-shape variables done in collaboration with Yu. Dokshitzer, A. Lucenti and G. Salam. We show that the one-loop result is modified by a rescaling factor (the Milan factor) which is the same for the class of jet-shape distributions including thrust, C-parameter, invariant jet masses, jet broadening and for the energy-energy correlation.
