Prospects of $CP$ violation in $\Lambda$ decay with polarized electron beam at STCF

Sheng Zeng, Yue Xu, Xiao Rong Zhou +2

Based on $1.89\times 10^8$ $J/\psi \to \Lambda \bar{\Lambda }$ Monte Carlo (MC) events produced from a longitudinally-polarized electron beam, the sensitivity of $CP$ violation of $\Lambda$ decay i…
