This volume is about newest developments in three subfields of theoretical high-energy physics: particle phenomenology, string theory and theoretical cosmology. At the start of a new millennium these fields show an unprecedented and exciting amount of mutual dependence and interaction. 

Students, researchers, and engineers in theoretical and experimental particle physics.
