We propose to measure the decay asymmetry parameters in the hadronic weak decays of singly charmed baryons, such as ,Σ0π+,pK̄0, and . The joint angular formulae for these processes are presented, and are used to extract the asymmetry parameters in e+e− annihilation data. Base on the current data set...

Summary:We propose to measure the decay asymmetry parameters in the hadronic weak decays of singly charmed baryons, such as ,Σ0π+,pK̄0, and . The joint angular formulae for these processes are presented, and are used to extract the asymmetry parameters in e+e− annihilation data. Base on the current data set collected at BESIII, we estimate the experimental sensitivities to measure the parameters αΛπ+ for , αΣ+π0 for and αΣ0π+ for .
