DESCRIPTION:I present recent methods to obtain the analytic form of two-lo
 op helicity amplitudes in QCD. The results are analytically reconstructed 
 from exact numerical evaluations over finite fields. The evaluations of th
 e amplitudes are performed with the numerical unitarity approach\, which w
 ill be discussed in some detail. In addition to the unitarity properties g
 eometric properties of the amplitudes are used to simplify the computation
