The two-loop fully differential soft function for $$Q\overline{Q }V$$ production at lepton colliders

Abstract We consider the production of a pair of heavy quarks $$Q\overline{Q }$$ in association with a generic colour singlet system V at lepton colliders, and present the first analytic calculation of the two-loop soft function differential in the total momentum of the real radiation. The calculati...
