Query: Z Polarization in $e^+e^-\to t\bar t Z$ for testing the top quark mass
  structure and the presence of final interactions   We show that the measurement of the $Z$ polarization in the $e^+e^-\to t\bar
t Z$ process would allow an interesting determination of the role of the top
quark mass. This can be used for testing the possibility of top compositeness
or of the occurence of final state interactions related to the mass generation
in particular the interaction with dark matter.
