Sažetak
In this article we propose standard model strictly forbidden decay modes, quarkonia (QQ(1^{; ; ; ; ; --}; ; ; ; ; ) = J/psi, Upsilon) decays into two photons, as a possible signature of the space-time non- commutativity. An experimental discovery of J/psi -> gamma gamma and/or Upsilon -> gamma gamma processes would certainly indicate a violation of the Landau-Pomeranchuk-Yang theorem and a definitive appearance of new physics.
