Noncommutative Standard Model in Top Quark Sector
  In this article we aim to estimate the bounds on the noncommutative scale $\Lambda_{NC}$ and to extract the 95% exclusion contours for some $\theta_{\mu\nu}$ components using the recent measurements of the top quark width and the $W$ boson polarization in top pair events from CDF experiment at Tevatron.
