✦ Synopsis

The NNLO QCD corrections to the e + e -→ 3 jets can be decomposed according to their colour factors. Out of the seven colour factors, three are of QED-type: 1/N 2 , NF /N and N 2 F . We use the antenna subtraction method to compute these contributions, providing complete expressions for the subtraction terms in NF /N and N 2 F .
