Auriemma 2007 constraints on CPT vialation review

主要内容:
Introduced the basic method on how to do the constraints -- purturbation expansion.

Including the work on GRBs, which is the Lorentz Violation to constrain the quantum gravity.

Title: CPT violations in Astrophysics and Cosmology
Authors: G. Auriemma
Comments: 13 pages, Invited Paper to the Frascati Workshop 2007 Vulcano (Italy), May 28 - June 2, 2007
Subjects: Astrophysics (astro-ph)

In this paper it is given a brief review of the current limits on the magnitude of CPT and Lorentz Invariance violations, currently predicted in connection with quantum gravity and string/M-theory, that can be derived from astrophysical and cosmological data. Even if not completely unambiguous, these observational tests of fundamental physics are complementary to the ones obtained by accelerator experiments and by ground or space based direct experiments, because potentially can access very high energies and large distances.
