Abstract
We apply the relativistic Bethe-Salpeter formalism to the calculation of final-state effects in the production of a t ($) over bar t pair at threshold. We find that final-state rescattering does not affect the momentum distribution of the t ($) over bar t pair to lowest order in the strong coupling constant. This result correctly extends earlier re sults based on the non-relativistic Lippmann-Schwinger equation.
