Abstract
We present a measurement of top quark polarization in pair production in collisions at using data corresponding to of integrated luminosity recorded with the D0 detector at the Fermilab Tevatron Collider. We consider final states containing a lepton and at least three jets. The polarization is measured through the distribution of lepton angles along three axes: the beam axis, the helicity axis, and the transverse axis normal to the production plane. This is the first measurement of top quark polarization at the Tevatron using final states and the first measurement of the transverse polarization in production. The observed distributions are consistent with standard model predictions of nearly no polarization.
