    Title: Strangeness with ALICE: from pp to Pb-Pb
    Author: Abelev, Betty
    Contributor: Abelev, Betty (pacrepositoryorg)
    Subject: Collisions ; Strangeness ; Gluons ; Quarks ; Hadrons ; Large Hadron Collider ; Quark-Gluon Plasma ; Nucleons
    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).

    Title: Measurement of prompt D-meson production in p-Pb collisions at $\sqrt{s_{NN}}$ =5.02TeV

    Description: The pT-differential production cross sections of the prompt charmed mesons $D^0, D^+, D^{*+}$ and $D_s^+$ and their charge conjugate in the rapidity interval -0.96 $y_{cms}$ 0.04 were measured in p-Pb collisions at a centre-of-mass energy $\sqrt{s_{NN}}$ = 5.02 TeV with the ALICE detector at the LHC. The nuclear modification factor $R_{pPb}$, quantifying the D-meson yield in p--Pb collisions relative to the yield in pp collisions scaled by the number of binary nucleon-nucleon collisions, is compatible within the 15-20% uncertainties with unity in the transverse momentum interval 1 $p_T$ 24 GeV/c. No significant difference among the $R_{pPb}$ of the four D-meson species is observed. The results are described within uncertainties by theoretical calculations that include initial-state effects. The measurement adds experimental evidence that the modification of the momentum spectrum of D mesons observed in Pb-Pb collisions with respect to pp collisions is due...

    Subject: Physics
    Description: We present the first measurement at the LHC of exclusive J/ψ photoproduction off protons, in ultraperipheral proton-lead collisions at √sNN=5.02  TeV. Events are selected with a dimuon pair produced either in the rapidity interval, in the laboratory frame, 2.5y4 (p−Pb) or −3.6y−2.6 (Pb−p), and no other particles observed in the ALICE acceptance. The measured cross sections σ(γ+p→J/ψ+p) are 33.2±2.2(stat)±3.2(syst)±0.7(theor)  nb in p−Pb and 284±36(stat)+27−32(syst)±26(theor)  nb in Pb−p collisions. We measure this process up to about 700 GeV in the γp center of mass, which is a factor of two larger than the highest energy studied at HERA. The data are consistent with a power law dependence of the J/ψ photoproduction cross section in γp energies from about 20 to 700 GeV, or equivalently, from Bjorken x scaling variable between ∼2×10−2 and ∼2×10−5, thus indicating no significant change in the gluon density behavior of the proton between HERA and LHC energies....

    Title: Multi-strange baryon correlations at RHIC
    Author: Abelev, Betty
    Contributor: Abelev, Betty (pacrepositoryorg)
    Subject: Quarks ; Baryons ; Elongation ; Correlation ; Dependence
    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.
