Cpt-and Lorentz-symmetry Breaking: a Review
نویسنده
چکیده
The breakdown of spacetime symmetries has recently been identified as a promising candidate signal for underlying physics, possibly arising through quantum-gravitational effects. This talk gives an overview over various aspects of CPTand Lorentz-violation research. Particular emphasis is given to the interplay between CPT, Lorentz, and translation symmetry, mechanisms for CPT and Lorentz breaking, and the construction of a low-energy quantumfield description of such effect. This quantum field framework, called the SME, is employed to determine possible phenomenological consequences of CPT and Lorentz violation for neutral-meson interferometry.

The Status of Cpt
A short review is given of some theoretical approaches to CPT violation. A potentially realistic possibility is that small apparent breaking of CPT and Lorentz symmetry could arise at the level of the standard model from spontaneous symmetry breaking in an underlying theory. Some experimental constraints are described.
متن کاملElectromagnetic Tests of Lorentz and Cpt Symmetry
In recent years, there has been a growing interest in testing Lorentz and CPT symmetry. This is due to both theoretical developments as well as improved experimental capabilities. For example, it has been shown that string theory can lead to violations of CPT and Lorentz symmetry. This is because strings are nonpointlike and have nonlocal interactions. They can therefore evade the CPT theorem. ...
متن کاملTheoretical Analysis of Cpt and Lorentz Tests in Penning Traps
The CPT theorem has been tested to very high precision in a variety of experiments involving particles and antiparticles confined within Penning traps. These tests include comparisons of anomalous magnetic moments and charge-to-mass ratios of electrons and positrons, protons and antiprotons, and hydrogen ions and antiprotons. We present a theoretical analysis of possible signals for CPT and Lor...
متن کاملTesting CPT with B Mesons
Apparent violations of CPT and Lorentz symmetry might arise in nature as a result of spontaneous symmetry breaking in a theory beyond the standard model. This talk summarizes a few relevant theoretical and experimental issues, with some emphasis on implications for CPT tests with neutral-B mesons.
متن کاملNo CPT Violation from Tilted Brane in Neutral Meson−Antimeson Systems
Tilted brane in theories with large compact extra dimensions leads to spontaneous symmetry breaking of the Lorentz and rotational invariance in four dimensions, as shown by Dvali and Shifman. In this brief report, we point out that the mentioned Lorentz symmetry breaking, although leading to the CPT–violating interaction terms, cannot lead to the CPT violation in the experimentally interesting ...
