Laboratory frame analysis of $e^+ e^- \to μ^+ μ^-$ scattering in the Noncommutative Standard Model

We study the muon pair production $ e^+ e^- \to μ^+ μ^-$ in the framework of the non-minimal noncommutative(NC) standard model to the second order of the NC parameter $Θ_{μν}$. The $\mathcal{O}(Θ^2)$ 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 analyse the time-averaged and time dependent observables in detail. The time-averaged azimuthal distribution of the cross section shows siginificant departure from the standard model. We find strong dependence of the total cross section(time- averaged) and their distributions on the orientation of the noncommutative electric vector (${\vecΘ}_E$). The periodic variation of the total cross-section with time over a day seems to be startling and can be thoroughly probed at the upcoming Linear Collider(LC).
