Strangeness production in the NA61/SHINE experiment at the CERN SPS energy range

NA61/SHINE is a multi-purpose fixed-target experiment located at the H2 beamline of CERN North Area. One main goals to study phase transition and search for critical point strongly interacting matter. Strangeness production long-known valuable probe understanding particle in high-energy physics due absence strange valence quarks initial collision state.
