Non-Pauli Transitions from Spacetime Noncommutativity

The consideration of noncommutative spacetimes in quantum theory can be plausibly advocated from physics at the Planck scale. Typically, this noncommutativity is controlled by fixed 'vectors' or 'tensors' with numerical entries like {theta}{sub {mu}{nu}}for the Moyal spacetime. In approaches enforcing Poincare invariance, these deform or twist the method of (anti)symmetrization of identical particle state vectors. We argue that the Earth's rotation and movements in the cosmos are 'sudden' events to Pauli-forbidden processes. This induces (twisted) bosonic components in state vectors of identical spinorial particles. These components induce non-Pauli transitions. From known limits on such transitions, we infer that the energy scale for noncommutativity is > or approx. 10{sup 24} TeV. This suggests a new energy scale beyond the Planck scale.
