Abstract (excerpt)
We explore a new approach to search for a low-mass $Z^{\prime}$ particle through $J/ψ$ decays by identifying its existence through parity-violating phenomena in the isospin-violating final states of $Λ\overlineΣ^{0}$ and the corresponding charge conjugated states of $\overlineΛΣ^{0}$. Our investigation centers on a generation-independent and leptophobic $Z^{\prime}$ with its mass below 10 GeV. Given the present experimental conditions at the Beijing Spectrometer III~(BESIII) and the anticipated opportunities at the Super Tau Charm Factory~(STCF), we conduct Monte-Carlo simulations to predict p
