Study of some physical models in the framework of noncommutative geometry

Abstract

We discuss the limits on the scale of the noncommutative (NC) parameter ΛNC via studying the top-quark pair production through electron-positron collision in the framework of the minimal noncommutative standard model (mNCSM),using the Seiberg-Witten(SW) maps to the first order of the NC parameter Θμν. In this work we assume an ansatz for the NC parameter Θμν and we find new limit on the NC scale ΛNC, which is in the range 0.1-0.2 TeV. We confirm the results obtained in muon pair production.
