Abstract
The antenna subtraction formalism allows to calculate QCD corrections to jet observables Within this formalism the subtraction terms are constructed using antenna functions describing all unresolved radiation between a pair of hard radiator partons In this paper we focus on the subtraction terms for double real radiation contributions to jet observables in hadronhadron collisions evaluated at NNLO An essential ingredient to these subtraction terms are the fourparton antenna functions with both radiators in the initial state We outline the construction of the double real subtraction terms classify all relevant antenna functions and describe their integration over the relevant antenna phase space For the initialinitial antenna functions with two quark flavours we derive the phase space master integrals and obtain the integrated antennae
