The two volumes that comprise String Theory provide an up-to-date, comprehensive account of string theory. Volume 1 provides a thorough introduction to the bosonic string, based on the Polyakov path integral and conformal field theory. The first four chapters introduce the central ideas of string theory, the tools of conformal field theory, the Polyakov path integral, and the covariant quantization of the string. The book then treats string interactions: the general formalism, and detailed treatments of the tree level and one loop amplitudes. Toroidal compactification and many important...

Volume 2: Superstring Theory and Beyond, begins with an introduction to supersymmetric string theories and goes on to a broad presentation of the important advances of recent years. The book first introduces the type I, type II, and heterotic superstring theories and their interactions. It then goes on to present important recent discoveries about strongly coupled strings, beginning with a detailed treatment of D-branes and their dynamics, and covering string duality, M-theory, and black hole entropy, and discusses many classic results in conformal field theory. The final four chapters are...

This text introduces the theoretical framework for describing the quark-gluon plasma, an important new state of matter. The first part of the book is a self-contained introduction to relativistic thermal field theory. Topics include the path integral approach, the real and imaginary time formalisms, fermion fields and gauge fields at finite temperature. The author illustrates useful techniques such as the evaluation of frequency sums and the use of cutting rules. The second part of the book is devoted to recent developments, and gives a detailed account of collective excitations (bosonic and...
