摘要：

At future γγ colliders copious production of t t̄ pairs is possible. This would allow for a detailed investigation of the interactions involving the top quark. We propose some correlations which are sensitive to t t̄ final state interactions and we compute the QCD and standard model Higgs boson contributions to these correlations. A correlation resulting from the QCD induced transverse polarization of top quarks is found to be sizable and measurable at a high energy e+e- collider, which is operated as a photon collider through backscattering of laser photons, at an integrated luminosity of 10 fb-1. © 1995 The American Physical Society.
