Abstract
In this talk it is shown how to formulate gauge theories relevant to
particle physics on a noncommutative spacetime. One of the key problems is
to understand how to formulate symmetries on a noncommutative spacetime.
We shall explain how to formulate SU(N) gauge symmetries and Lorentz
symmetry on these spaces. We then explain how to quantize field theories
formulated on such a spacetime and apply our results to QED and GUT
theories. We then describe experimental bounds on the scale for spacetime
noncommutativity.
