LABORATORY FRAME ANALYSIS OF e+e- → μ+μ- SCATTERING IN THE NONCOMMUTATIVE STANDARD MODEL AT LINEAR COLLIDER

We study the muon pair production e(+)e(-) -> mu(+)mu(-) in the framework of the nonminimal noncommutative standard model (NCSM) to the second-order of the noncommutative (NC) parameter Theta(mu nu) at linear collider. The O(Theta(2)) momentum-dependent NC interaction significantly modifies the cross-section and angular distributions which are different from the standard model. After including the effects of earth's rotation we analyze the time-averaged and time-dependent observables in detail. The time-averaged azimuthal distribution of the cross-section shows significant departure from the standard model which can be tested at the upcoming linear collider. We find strong dependence of total cross-section (time-averaged) and their distributions on the orientation and the magnitude of the NC electric vector (Theta(E)). Assuming that the future linear collider data will differ from the standard model result by 5%, we obtain Lambda >= 615 GeV and Lambda >= 946 GeV corresponding to the machine energy E-com = 1000 GeV and 1500 GeV.
