Gluon Polarization in e+e- t tG
Abstract
We calculate the linear polarization of gluons radiated off top quarks produced in e+e- annihilations. For typical top pair production energies at the Next-Linear-Collider (NLC) the degree of linear polarization remains close to its soft gluon value of 100% over almost the whole energy spectrum of the gluon. The massive quark results are compared with the corresponding results for the massless quark case.
