The infrared structure of e+e- → 3 jets at NNLO reloaded

This paper gives detailed information on the structure of the infrared singularities for the process e(+)e(-) -> 3 jets at next-to-next-to-leading order in perturbation theory. Particular emphasis is put on singularities associated to soft gluons. The knowledge of the singularity structure allows the construction of appropriate subtraction terms, which in turn can be implemented into a numerical Monte Carlo program.
