Spin measurements in strangeness production at the LHC

Abstract

We briefly recollect the problem of significant hyperon polarization emphasizing the role of spin in dynamics of hadron interactions. We provide also some model predictions based on chiral dynamics and the impact parameter picture for illustration. The old, but yet unsolved problem of hyperon polarization, can obtain a new insight from the measurements at the LHC energies and, in combination with other measurements, can be used for tagging QGP formation in $pp$--collisions.
