Query: Signatures of New Physics from HBT Correlations in UHECRs   Quantum fields written on noncommutative spacetime (Groenewold - Moyal plane)
obey twisted commutation relations. In this paper we show that these twisted
commutation relations result in Hanbury-Brown Twiss (HBT) correlations that are
distinct from that for ordinary bosonic or fermionic fields, and hence can
provide us useful information about underlying noncommutative nature of
spacetime. The deviation from usual bosonic/fermionic statistics becomes
pronounced at high energies, suggesting that a natural place is to look at
Ultra High Energy Cosmic Rays (UHECRs). Since the HBT correlations are
sensitive only to the statistics of the particles, observations done with
UHECRs are capable of providing unambiguous signatures of noncommutativity,
without any detailed knowledge of the mechanism and source of origin of UHECRs.
