Probing the quark-gluon plasma in ultrarelativistic heavy-ion collisions — •Alice Ohlson — Physikalisches Institut, Universität Heidelberg

In high-energy collisions of heavy nuclei, such as in collisions of lead ions at the Large Hadron Collider, the resulting state of matter attains such high temperatures and energy densities that quarks and gluons are no longer confined into hadrons. Known as the quark-gluon plasma (QGP), this matter occupies the high-temperature and high-density regime of the phase diagram of quantum chromodynamics (QCD). By probing the properties of the QGP, we are able to study QCD and the strong nuclear force in the extreme high temperature limit.

In this talk, a selection of key measurements will be presented which give insight into the space-time evolution of the QGP and its thermodynamical and hadrochemical properties, with particular emphasis placed on single- and multi-particle measurements of (un)identified light hadrons.
