Recent results on Strangeness Production in STAR
(oral presentation)

Due to its large acceptance, the STAR experiment has acquired a wealth of data on strangeness production for a variety of collision systems and energies, from p+p up to Au+Au. I will start this presentation by using the yields and spectra to address the evolution of the bulk system; including strangeness enhancement and the flavour dependence of radial and elliptic flow. I will then concentrate on strangeness production in the intermediate and high pT regions. Utilising the fact that we can identify strange baryons and mesons, we investigate different hadronization mechanisms. The ratios of the particle yields, measured to high pT, are used to further investigate the range and applicability of the previously reported anomalous baryon production. We also study two-particle azimuthal correlations of identified particles in order to investigate any flavour dependence of jet fragmentation in the available pT range. Data will be presented for a number of different collision systems and energies.
