X(16.7) production in electron–positron collision

Abstract The anomaly found in the excited $$^8\text {Be}$$ 8Be nuclear transition to its ground state is attributed to a spin-1 gauge boson X(16.7). To hunt for this boson, we propose two traps: $$e^+e^-\rightarrow X\gamma $$ e+e-→Xγ and $$J/\psi \rightarrow X\gamma $$ J/ψ→Xγ , both following with $...
