The Phases Of Quantum Chromodynamics

E-Book Overview

This book discusses the physical phases of Quantum Chromodynamics (QCD) in ordinary environments, as well as in extreme environments with high temperatures and high baryon numbers. Under such extreme conditions, new phases are thought to exist: the quark-gluon plasma and color superconductivity. After introducing lattice gauge theory, John Kogut and Mikhail Stephanov emphasize the application of QCD to the study of matter in extreme environments through a host of methods. These include lattice gauge theory, lower dimensional model field theories and effective Lagrangians.

E-Book Content

This page intentionally left blank The Phases of Quantum Chromodynamics This book discusses the physical phases of quantum chromodynamics (QCD) in ordinary as well as in extreme environments of high temperatures and high baryon number. A major theme of this book is the idea that, to understand the dynamics of QCD in ordinary circumstances, one needs to master them in extreme environments. QCD is thought to be characterized in ordinary circumstances by quark confinement through the formation of flux tubes and chiral-symmetry breaking. These properties are believed to be lost in environments of extreme conditions and new phases, the quark–gluon plasma and color superconductivity, are thought to exist. The book is aimed at graduate students and researchers entering the fields of lattice-gauge theory, heavy-ion collisions, nuclear theory, and high-energy phenomenology, as well as astrophysicists interested in the phases of nuclear matter and their impact on our current ideas of the interiors of dense stars. It is suitable for use as a textbook on lattice-gauge theory, effective Lagrangians, and field-theoretical modeling for nonperturbative phenomena in QCD.
