摘要

Although J/Ψ weak decays are rare,they are possible within the standard model of elementary particles.Inspired by the potential prospects of the future intensity frontier,the C parity violating J/Ψ → πη('),ηη'decays and the strangeness changing J/ψ→ πK,Kη(')decays are studied via the perturbative QCD approach.It is determ-ined that the J/Ψ → ηη'decays have relatively large branching ratios,approximately on the order of 10-11,which might be within the measurement capability and sensitivity of the future STCF experiment.
