Description

I will give an overview of spin polarisation and correlation effects in baryon-antibaryon pair production at electron-positron colliders. General formalism and methods for measuring the polarisation of the baryons and determining the properties of the production reactions will be introduced. Precision studies of the spin properties were enabled, thanks to millions of hyperon-antihyperon pairs collected by BESIII. Such studies include the measurement of hyperon decays, electromagnetic form factors, searches for electric dipole moments, and tests of quantum mechanics.
