Future hadron collider experiments are expected to record large to huge samples of t t events. The analysis of these data with respect to t t spin-spin correlations requires precise predictions of the production of these quark pairs in a general spin configuration. Therefore we have computed, at next-to-leading order (NLO) in the QCD coupling, the spin density matrices describing t t production by quark antiquark annihilation, which is the dominant production process at the Tevatron. Moreover we have computed the strength of the t t spin correlation at NLO, using various spin quantization axes.
