Phenomenological study of decays*

Year: 2023

Type: article

Abstract: The measurement of decay parameters is one of the important goals of particle physics experiments, and the measurement serves as a probe to search for evidence of CP violation in baryonic decays. The experimental results will aid in advancing existing theoretical research and establishing new experimental objectives. In this study, we formulate the asymmetric parameters that characterize parity violation, and then derive formulas for the measurement of CP violation. The formulae for the joint angular distribution of the full decay chain as well as the polarization observable of , , Λ, and are also provided for experiments. Lastly, we evaluated the sensitivity of two asymmetric parameters: (abbreviated as ) and (abbreviated as ) for future experimental measurements.
