We compute the three-loop helicity amplitudes for the scattering of fourgluons in QCD. We employ projectors in the 't Hooft-Veltman scheme andconstruct the amplitudes from a minimal set of physical building blocks, whichallows us to keep the computational complexity under control. We obtainrelatively compact results that can be expressed in terms of harmonicpolylogarithms. In addition, we consider the Regge limit of our amplitude andextract the gluon Regge trajectory in full three-loop QCD. This is the lastmissing ingredient required for studying single-Reggeon exchanges atnext-to-next-to-leading logarithmic accuracy.
