Prospects of CP violation in Λ decay with a polarized electron beam at the STCF*

Abstract

Abstract Based on Monte Carlo (MC) events produced from a longitudinally-polarized electron beam, the sensitivity of the violation of Λ decay is studied using fast simulation software. In addition, the decay can be used to optimize the detector response using the interface provided by the fast simulation software. In the future, the STCF is expected to obtain 3.4 trillion events, and the statistical sensitivity of the violation of Λ decay via the process is expected to reach when the electron beam polarization is 80%.
