We discuss the non-commutative extension of the standard model constructed with the Seiberg-Witten maps for SU(3)_C x SU(2)_L x U(1)_Y. Using the first-order approximation in the non-commutative parameters theta, we estimate the sensitivity…

We consider the role of Lorentz symmetry in noncommutative field theory. We find that a Lorentz-violating standard-model extension involving ordinary fields is general enough to include any realisitc noncommutative field theory as a subset.…

In the standard model production of on-shell Z boson at a photon collider (or Z decays into $\gamma\gamma$) is strictly forbidden by angular momentum conservation and Bose statistics (the Yang's Theorem). In the standard model with…
