Studying the Quark-Gluon Plasma in Nuclear Collisions at the LHC

*ABSTRACT*

The theory of the strong interaction, quantum-chromodynamics, predicts 
for high temperature and density a new state of matter in which the 
confinement of quarks and gluons is lifted. This state, the quark-gluon 
plasma, existed in the early universe after the electro-weak phase 
transition up to about 10 microseconds. In the past 25 years, 
accelerator-based experiments have been conducted in order to recreate 
this state of matter for a short time. The ideal tool is collisions of 
heavy nuclei at energies as high as possible. Now with the Large Hadron 
Collider (LHC) at CERN, an entirely new energy regime is accessible. 
Since November 2010, collisions of lead nuclei at the LHC have been 
studied in three experiments. In this talk, selected first results from 
the ALICE experiment will be presented and discussed in the context of 
results at lower beam energies and theoretical interpretation.
