Abstract
We derive the integrated forms of specific initial-final tree-level four-parton antenna functions involving a massless initial-state parton and a massive final-state fermion as hard radiators. These antennae are needed in the subtraction terms required to evaluate the double real corrections to tt¯ hadronic production at the NNLO level stemming from the partonic processes qq¯¯→tt¯q′q¯¯′ and gg→tt¯qq¯¯.
