Abstract: The proper incorporation of spin effects in r lepton decays is often of importance. In the present work the case of the Z /+ —a t + t “ production mechanism is studied in detail. As an example, the effects due to the spin correlations on the potential for the Minimal Supersymmetric Standard Model (MSSM) Higgs boson (s) searches in the t t decay channel a t the Large Hadron Collider (LHC) are discussed. For these processes, the Standard Model Zfy* - a r r -p a ir production is a dominant background. The spin effects in high energy physics reactions, can be implemented up to certain approximation, independently of the algorithm and matrix elements used by the production program. Information stored on every generated event can be sufficient. The algorithm based on such approximation is documented. Question of the theoretical uncertainty is partly discussed.
