Abstract
In this article we propose standard model strictly forbidden decay modes, quarkonia () decays into two photons, as a possible signature of space-time noncommutativity. An experimental discovery of and/or processes would certainly indicate a violation of the Landau-Pomeranchuk-Yang theorem and a definitive appearance of new physics.
