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).
