The Early Universe

This book describes the connections which have been developed in recent years between particle physics and cosmology. Many theories have been developed to describe the fundamental interaction of elementary particles in the extremely high temperatures of the early universe. The author presents an up-to-date picture of this rapidly changing field, taking care to sort out speculations from well-established results. Two groups of readers are addressed. On the one hand an astronomer or student in astronomy can use this book to understand the implications for cosmology of particle physics. On the other hand an interested particle physicist can read it to become acquainted with the basic facts of cosmology.
