Gluon polarization ine+e−→tt¯G

subject

description

We calculate the linear polarization of gluons radiated off top quarks produced in e{sup +}e{sup {minus}} annihilations. For typical top quark pair production energies at the Next Linear Collider the degree of linear polarization remains close to its soft gluon value of 100{percent} over almost the whole energy spectrum of the gluon. The massive quark results are compared with the corresponding results for the massless quark case. {copyright} {ital 1997} {ital The American Physical Society}
