New Signature of low mass $Z^{\prime }$ in $J/\ddot{I}ˆ$ decays

Chao-Qiang Geng, Chia-Wei Liu, Jiabao Zhang

We explore a new approach to search for a low-mass $Z^{\prime }$ particle through $J/\ddot{I}ˆ$ decays by identifying its existence through parity-violating phenomena in the isospin-violat…
