TeV-photon paradox and space with SU(2) fuzziness
Ahmad Shariati, Mohammad Khorrami, Amir H. Fatollahi
TL;DR
This paper explores a model of space noncommutativity based on SU(2) algebra to explain how multi-TeV photons from distant sources can reach Earth, potentially preventing pair production with CMB photons.
Contribution
It introduces a space noncommutativity model using SU(2) algebra that could account for high-energy photon propagation over cosmological distances.
Findings
Pair production with CMB photons may be kinematically forbidden in this model.
The SU(2) fuzziness of space could resolve the TeV-photon paradox.
The model suggests new physics for photon propagation at high energies.
Abstract
The possibility is examined that a model based on space noncommutativity of linear type can explain why photons from distant sources with multi-TeV energies can reach earth. In particular within a model in which space coordinates satisfy the algebra of SU(2) Lie group, it is shown that there is the possibility that the pair production through the reaction of CMB and energetic photons would be forbidden kinematically.
