Description
ACCOUNTING PRINCIPLES Meeting the need for a coherently written and comprehensive compendium combining field theory and particle physics for advanced students and researchers, this volume directly links the theory to the experiments. It is clearly divided into two sections covering approaches to field theory and the Standard Model, and rounded off with numerous useful appendices. A timely work for high energy and theoretical physicists, as well as astronomers, graduate students and lecturers in physics.
From the contents:
Particles and Fields
Lorentz Invariance
Dirac Equation
Field Quantization
Scattering Matrix
QED: Quantum Electrodynamics
Radiative Corrections and Tests of Qed
Symmetries
Path Integral : Basics
Path Integral Approach to Field Theory
Accelerator and Detector Technology
Spectroscopy
The Quark Model
Weak Interaction
Neutral Kaons and CP Violation
Hadron Structure
Gauge Theories
Appendices
Volume 2 (2013, ISBN 3-527-40966-1) will concentrate on the main aspects of the Standard Model by addressing its recent developments and future prospects. Furthermore, it will give some thought to intriguing ideas beyond the Standard Model, including the Higgs boson, the neutrino, the concepts of the Grand Unified Theory and supersymmetry, axions, and cosmological developments.
