@article{Kamoshita2007ProbingNS, title={Probing noncommutative space-time in the laboratory frame}, author={Jun-ichi Kamoshita}, journal={The European Physical Journal C}, year={2007}, volume={52}, pages={451-457} }

The phenomenological investigation of noncommutative space-time in the laboratory frame is presented. We formulate the apparent time variation of noncommutativity parameter θμν in the laboratory frame due to the earth’s rotation. Furthermore, in the noncommutative QED, we discuss how to probe the electric-like component θE=(θ01,θ02,θ03) by the process $e^-e^+\rightarrow\gamma\gamma$ at future e-e+ linear collider. We may determine the magnitude and the direction of θE by detailed study of the…
