      Title: Semi-leptonic decay of a polarized top quark in the noncommutative standard model
      Author(s): mojtaba Mohammadi Najafabadi
      Status: Published
      Journal: Phys. Rev. D
      Vol.: 1
      Year: 2006
      Pages: 9
      Supported by: IPM
      Abstract:
    In this paper we study the noncommutative effects to the lepton spectrum from the decay of a polarized top quark. It is shown that the lowest contribution comes from the quadratic terms of the noncommutative parameter. The deviations from the standard model are significant for small values of the noncommutative characteristic scale. However, the charged lepton spin correlation coefficient has a remarkable deviation from the standard model from very low values of the noncommutative characteristic scale to 1 TeV.
