Third Meeting on CPT and Lorentz Symmetry: Proceedings of the Indiana University, Bloomington, USA 4-7 August 2004

Lorentz and CPT invariance is a feature of the Standard Model of particle physics and of theories of gravity such as Einstein's general relativity. However, an underlying theory such as strings may introduce small violations of Lorentz and CPT symmetry. This book consists of reviews from about 50 experts in the field, covering theoretical and experimental studies of these relativity-violating effects. The Meeting focuses on recent developments involving fundamental spacetime symmetries and included theoretical scenarios and experimental searches for possible relativity violations. Experimental subjects covered include resonantcavity and interferometric behavior of photons, neutrino oscillations, oscillations and decays of K, B, D mesons, clock-comparison measurements, space-based tests, astrophysical observations, spinpolarized matter, particle-antiparticle comparisons, spectroscopy of hydrogen and antihydrogen, muon behavior, and gravitational tests. Theoretical topics covered include physical effects at the level of the Standard Model and beyond, the possible origins and mechanics for Lorentz and CPT violations, and associated issues in field theory, particle physics, gravity, and string theory.
