aThe authors propose some CP odd observables to test CP invariance in the tt system produced at pp and pp colliders.

Using these observables the effects of CP violation from the production and from the decay of the top quarks can be

separated well. The application of their observables to pp collisions, where one has no CP invariant initial state, is

discussed. To parametrize CP violating interactions their use an effective lagrangian for the tt production and a general

form factor approach for the decay of t and t (19 Refs.)^^ ^_aEnglish^^ ^_aCP invariance^^ ^_aform factors
