摘要: Is it possible to detect a new weakly coupled force at the QCD scale that interacts primarily with quarks? This work investigates experimental signatures of MeV–GeV gauge boson couples baryon number, attention 100 MeV–GeV mass range is regime nonperturbative QCD. Such state can be searched for in rare radiative decays light mesons ( η , ′ ϕ ω ) as π 0 γ resonance, which its leading decay mode from 140 620 MeV. discovery window forces beyond Standard Model not covered by existing dark photon searches.
