Heavy-Ion Physics (QCD under Extreme Conditions) First question you should ask: WHY??
Motivation and some disturbing facts
Collective effects x “fundamental” physics
Second question you should ask: WHERE??
Accelerator experiments, astro, early universe
My focus: the EoS
Third question you should ask: HOW??
Theory, models, etc Effective model building
Z(N), the Polyakov loop, and confinement
Chiral symmetry breaking
Two examples on relevance and difficulties in exploring the
phase diagram
Chiral magnetic effect and the strong CP problem
Drawing the phase diagram

1. Intro and QCD fundamentals • QCD is a good theory for
strong interactions: facts • From QED to QCD: the
importance of color • Renormalization group and
asymptotic freedom • Infrared safety
2. QCD in the final state • Infrared safety • Towards realistic final
states • Jets
3. From accurate QCD to useful QCD • DIS: from the parton model to
pQCD • Q2 Evolution and
PDF’s • pp collisions : a glimpse
