Reggeization in high energy QCD

We study QCD in the regime of high parton density arising in hadronic colli sions at large center-of-mass energy. The n-gluon amplitudes of the general ized leading logarithmic approximation are investigated. We find identities relating amplitudes with different numbers of gluons in the t-channel. The se identities constrain the reggeization of the gluon in high energy QCD. T he tensors describing the reggeization of a gluon in color space are identi fied.
