Written primarily for researchers and graduate students who are new in this emerging field, the book develops the necessary tools so that the readers can follow the latest advances in this subject. The readers are first guided to examine the basic informations from nucleon-nucleon collisions and the use of the nucleus as an arena to study the interaction of one nucleon with another. A survey of the relation between nucleon-nucleon and nucleus-nucleus collisions provides the proper comparison to study phenomena involving the more exotic quark-gluon plasma. Properties of the quark-gluon plasma and signatures for its detection are discussed to aid future searches and exploration for this exotic matter. Recent experimental findings are summarized.
