Abstract: (Elsevier)
We calculate the O(α s 2 ) corrections to the event shape in e + e − annihilation due to the parton processes e + e − → q q G , e + e − → q q qq and e + e − → q q GG . The event shape is characterized in an invariant way in terms of eigenvalues of an infrared-finite tensor. Working in the MS renormalization prescription the correction to the number of three-jet events is large. Reliable perturbative results will require the summation of large terms.
