Leptophobic dark photon interpretation of the η(′)→π0(η)γγ puzzle
The decays of η and η′ mesons provide unique opportunities for testing the properties of low energy Quantum Chromodynamics and for the search of new physics beyond the Standard Model. However, recent experimental results on the rare decays of η(′)→π0(η)γγ cannot be self-consistently described by the...
