Description
One of the key challenges of hadron physics today is understanding the origin of strangeness enhancement in high-energy hadronic collisions, i.e. the increase of (multi-)strange hadron yields relative to non-strange hadron yields with increasing charged-particle multiplicity. The microscopic origin of this phenomenon is still not fully understood: is it related to hard scattering events, such as jets, or instead to particle production mechanisms related to the underlying event? To separate strange hadrons produced in jets from those produced in the underlying event, the angular correlation between high-
