Prof. Berndt Mueller gave a lecture at the 34th International School of Nuclear Physics at the Center "Ettore Majorana" in Erice/Sicily, which was founded by the well known Italian physicist Antonino Zichichi. The School brought together approximately 100 young researchers and many leading scientists in the field of hot QCD matter. Mueller gave a lecture on event-by-event fluctuations in relativistic heavy ion collisions. Detailed information about the school can be found on the website here.
