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 the 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 characterise 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 (N$_{part}$).
