Heavy-Ion seminar by Marco van Leeuwen

Studying the Quark Gluon Plasma at the LHC with soft and hard probes

Abstract: The fundamental particles of the strong interaction, quarks and gluons, are normally confined in protons and neutrons inside nuclei. The goal of high-energy collisions of heavy nuclei is to create a state of matter where quarks and gluons are effectively free to move over larger distance, the Quark-Gluon Plasma (QGP), and to study its properties in the laboratory. I will present recent results from heavy ion collisions at the LHC and discuss what they tell us about the Quark Gluon Plasma. I will cover both soft probes, where azimuthal anisotropy of the particle emission tells us about flow fields in the QGP, and hard probes, i.e. high-pt particle production and jets, which probe the QGP by interactions.
