• A bstractWe present the NNLO corrections to top pair production in the quark-antiquark channel proportional to the number of light quark flavors Nl. While the double real corrections were derived previously, here we compute the real-virtual and virtual-virtual contributions in this partonic channel. Using the antenna subtraction formalism, we show that the subtraction terms correctly approximate the real-virtual contributions in all their infrared limits. Combined with the integrated forms of… CONTINUE READING
