摘要:
Decays of strange baryons provide complementary information to the decays of kaons for searches
of the physics beyond theStandard Model. Two possible strategies are represented in two reports
submitted to recentSnowmass APS study. The first is searches for rare and forbidden processes. 
The second issearches for CP violationin non-leptonic two-body weak decays of strangebaryons. 
The renewedinterest in the secondstrategy is due to thenovel method that was applied in series
of measurements at BESIII, including the recent results published in Nature Physics and Nature.
The method uses spin entangled and polarized hyperon-antihyperon pairs from J/ψ decays. In the 
talk I will describe the method and explain how the spin polarization and correlations 
contributions determine precision of theCPV tests. I will discusspossible CPV tests in strange
baryon decays at next generation electron-positron J/ψ factories. In particular benefits of 
using longitudinally-polarized electron beamswill be emphasized.
