摘要：

In this report we propose the Z ->gamma gamma decay as a process strictly forbidden in the standard model, suitable for the search of noncommutativity of coordinates at very short distances. We computed the Z ->gamma gamma partial width in the framework of the recently proposed one-loop renormalizable gauge sector of the noncommutative standard model. New experimental possibilities at the Large Hadron Collider are analyzed and a firm bound to the scale of noncommutativity parameter is set around 1 TeV.
