The Phase diagram of QCD

Lectures given at the Advanced School on Quark Gluon Plasma, held in IIT Mumbai, from July 3 to 13, 2007. This course was given between July 3 and 6. The tutorials were taken by Saumen Dutta.

Quark matter in the news

The biggest science news of 2005 was quark matter, according to the American Institute of Physics (AIP).

Quark matter may be a liquid, the relativistic heavy-ion collider at Brookhaven has declared on April 18, 2005.

Quark matter may have been discovered, is a claim by CERN on February 8, 2000.

The Phase diagram of QCD

Lecture 1: Thermodynamics and lattice gauge theory

Here are some notes on thermodynamics; this part of the lecture followed these notes. It would be useful also to read the article Thermodynamics, by M. J. Buckingham, in the book Phase Transitions and Critical Phenomena, vol 2, edited by C. Domb and M. S. Green (publishers: Academic Press, 1972).

Any introductory book on lattice gauge theory would cover the material that was lectured upon. For a heavy-ion physicist, the points of interest here are the kind of uncertainties, ie, systematic errors, that exist in lattice computations, and how to compare results from different groups.

Lecture 2: The Phase diagram of QCD

This lecture gave an overview of the phase diagram of QCD, and included the main qualitative conjectures and the current lattice results. Here are the major references.

Lectures 3 and 4: Properties of QCD matter

This part of the lectures concentrated on properties of QCD matter as found on the lattice and otherwise. Indispensable primary references are Statistical Mechanics and Fluid Dynamics by L. D. Landau and E. M. Lifschitz. The list of references for QCD matter is really large (and rap[idly growing), and it is not feasible to list them in their entirety. However, here are some which directly deal with material covered in the lectures and also point to other references.
