This partonic channel is the dominant component of the scattering process pp -> t-tbar-Z, which will be important for measuring the t-tbar-Z electroweak couplings. The O(alpha_s) corrections increase the total cross section by up to 75% for reasonable choices of the renormalization and factorization scales. Inclusion of these contributions descreases the residual scale dependence of the cross section coming from uncalculated higher order terms to +-5%.9 pages, 4 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - ExperimentNLO QCD corrections to the production of t-tbar-Z in gluon fusiontext
