Abstract
Recent results published in Nature Physics (2019) by the BESIII Collaboration revealed a substantial discrepancy in the Λ baryon decay parameter value compared to the world average at the time. This development was taken as the starting point for a feasibility study of CP violation tests in strange baryon decays at next-generation J/ψ factories. The proposed formalism allows for a direct comparison of particle and antiparticle properties, analyzing the weight of spin-correlation and polarization terms on such tests. The same weak nonleptonic decays can be studied using chiral perturbation theory (χPT), where S- and P-wave amplitudes are computed up to one-loop corrections. The behavior of such partial-wave amplitudes is investigated in light of the recent experimental updates and in a fully relativistic framework.
