    Title: Strangeness with ALICE: from pp to Pb-Pb
    Author: Abelev, Betty
    Subject: Nuclear Experiment ; High Energy Physics - Experiment
    Description: We present the measurements of strange and multi-strange hadrons in high energy pp and Pb-Pb collisions at the Large Hadron Collider (LHC) at CERN. The data for these measurements were collected by the ALICE detector in 2010 and 2011. By comparing strangeness data where Quark-Gluon Plasma (QGP) is not expected to be produced (pp collisions) with data where the energy-density of the collision is sufficient to produce the QGP (central and mid-central Pb-Pb collisions), we are able to investigate the properties of the QGP. We characterize the matter created in the collision by presenting strange and multi-strange particle spectra, yields, and transverse momenta in the context of increasing strangeness number, varying collision energy, and the number of nucleons participating in the collision (Npart). Comment: This is a proceedings for the Physics of the LHC 2012 Conference, held in Vancouver, BC

    Title: Multi-strange baryon correlations at RHIC
    Author: Abelev, Betty I.
    Subject: Nuclear Experiment
    Description: Multi-strange baryon azimuthal correlations were observed in d+Au and Au+Au data taken by the STAR detector at RHIC. We extract the same-side per-trigger yields for a variety of strange particle species and trigger pt, but do not observe any species dependence. We also report the observation of an elongation in the Delta-eta; direction of the Xi correlation peak, the ridge. Comparing the same-side yields in d+Au and Au+Au data, we conclude that the same-side yield of the azimuthal-only Xi correlations is greatly enhanced by the ridge yield. We also report the first observation of a strong same-side peak in the Omega baryon triggered azimuthal correlations. Comment: 8 pages, 4 figures
