چکیده
Infrared, optical, and ultraviolet spectropolarimetry of cosmological sources is used to constrain the pure electromagnetic sector of a general Lorentz-violating standard-model extension. The coefficients for Lorentz violation are bounded to less than 3 x 10(-32).

Astrophysical Tests of Lorentz Symmetry In
In this talk presented at the Fourth International Workshop on New Worlds in Astroparticle Physics, I discuss recent constraints on Lorentz violation in electrodynamics. The observed absence of birefringence of light that has propagated over cosmological distances bounds some coefficients for Lorentz violation to 2× 10.
متن کاملCosmological backgroung torsion limits from Lorentz violation
Cosmological limits on Lorentz invariance breaking in Chern-Simons (3 + 1) − dimensional electrodynamics are used to place limits on torsion. Birefrigence phenomena is discussed by using extending the propagation equation to Riemann-Cartan spacetimes instead of treating it in purely Riemannian spaces. The parameter of Lorentz violation is shown to be proportional to the axial torsion vector whi...

Lorentz violation is a promising candidate signal for Planck-scale physics [1]. For instance, it could arise in string theory [2] and is a basic feature of noncommutative field theories [3]. In quantum field theory at attainable energies, small violations can be incorporated into the standard model to yield a general Lorentzviolating standard-model extension [4]. Its lagrangian consists of all ...
متن کاملSpacetime Symmetries and Varying Scalars
This talk discusses the relation between spacetime-dependent scalars, such as couplings or fields, and the violation of Lorentz symmetry. A specific cosmological supergravity model demonstrates how scalar fields can acquire time-dependent expectation values. Within this cosmological background, excitations of these scalars are governed by a Lorentz-breaking dispersion relation. The model also c...
متن کاملIssues on Radiatively Induced Lorentz and Cpt Violation in Quantum Electrodynamics
Lorentz symmetry is algebraic foundation of the theory of special relativity. Nearly one hundred years the theory of special relativity keeps the status as a cornerstone of modern physics and has been supported by numerous high energy physics experiments and astrophysical observation. However, physics is a science born out of experimental observation. With the availability of higher precision e...
