Description

The study of the top-quark properties is one of the crucial points of the LHC physics program. The expected experimental precision on the measurement of the top-quark pair production cross section requires the calculation of the next-to-next-to-leading order (NNLO) corrections to this process in QCD. The calculation of the two-loop corrections to the top-quark pair production is an unavoidable step in the evaluation of the NNLO corrections, and poses interesting technical challenges. In this talk I will discuss the salient features of the calculation of the two-loop Feynman diagrams, and I will present analytic results for several sets of graphs in the quark annihilation production channel.
