We will do quizzes and other interactive class room activities. 

Here are the previous quiz questions with answers.


This lecture gives an introduction into ultra-relativistiv heavy-ion collisions and the physics of the quark-gluon plasma. It is aimed at Bacherlor, Master, and Diploma students as well as graduate students. Knowledge on the level of "Experimentalphysik IV" (PEP4) is sufficient for this basic introduction.
