Strange strangeness from NA61/SHINE
Strangeness production has been a subject of studies over 30 years. It is a key observable in one of the main goals of the NA61/SHINE experiment - in studying the onset of deconfinement. Due to properties of strange particles in hadronic matter and quark-gluon plasma, strangeness production is sensitive to the phase transition and provides indications of the onset of deconfinement. NA61/SHINE, a fixed target experiment at CERN SPS, measures strangeness production in p+p and ion-ion collisions in SPS energy range. This talk reviews a motivation to study the strangeness production as well as presents surprising results from NA61/SHINE and theoretical models.
