Production of two Z-bosons in gluon fusion in the heavy top quark approximation
We compute QCD radiative corrections to the continuum production of a pair of Z-bosons in the annihilation of two gluons. We only consider the contribution of the top quark loops and we treat them assuming that mt is much larger than any other kinematic invariant in the problem. We estimate the QCD...
