Beyond the Standard Model

This will be the most up-to-date graduate/professional-level textbook on high-energy physics on the market.. The recent dramatic discovery that the neutrino (a particle released in the nuclear reactions in the cores of stars) has a finite mass may very well change the face of physics; certainly it will change the Standard Model, a collection of fundamental theories of elementary particles. This new text replaces and updates the authors previous book, Modern Field Theory: A Primer , and gives the student or professional physicist a thorough comprehension not only of the fundamental theories and experimental results but also of the most recent and cutting-edge principles. }This book should be at the side of every particle and nuclear physics graduate student and professional. Journeys Beyond the Standard Model starts with a detailed and modern account of the Standard Model of elementary particle physics, the paradigm of particle physics for the last twenty years. Its timely release coincides with the recent dramatic discovery that the neutrino has a finite mass, which is the first indication that the Standard Model is an incomplete description of fundamental physics at short distances. This book presents in detail three possible generalizations of the Standard Model: its extension to accommodate neutrino masses; its extension to avoid CP violation in the strong interactions by introducing a new particle, the axion; and finally, its generalization to low-energy supersymmetry, which provides a link between the standard model and Einstein's theory of general relativity.This new graduate text complements the author's previous book, Modern Field Theory: A Primer , which focuses on the methodology of particle physics. Its aim is to give students and professional physicists alike a thorough comprehension of the phenomena described by the Standard Model, while keeping track of the most recent and cutting-edge principles of elementary particle physics. }
