Abstract

We present a new calculation of the O(2 s) coeecient of the energy-energy correlation function (EEC) using two diierent schemes to cancel infrared and collinear poles. The numerical evaluation uses the phase space slicing and the hybrid subtraction method. Both schemes converge with decreasing slicing cut. The results are independent of the scheme for small cuts. For the pure phase space slicing method, the cut must be below 10 ?6 to achieve good results. All four approaches agree with each other and connrm the results of Kunszt and Nason and Glover and Sutton, for the latter also with respect to contributions of diierent colour factors.
