Möller and Bhabha scattering in the noncommutative standard model

Abstract

We study the Möller and Bhabha scattering in the noncommutative extension of the standard model(SM) using the Seiberg-Witten maps of this to first order of the noncommutative parameter ${\theta }_{\mu \nu }$. We look at the angular distribution $d\sigma /d\Omega$ to explore the noncommutativity of space-time at around ${\Lambda }_{NC}\sim$ TeV and find that the distribution deviates significantly from the one obtained from the commutative version of the standard model.
