Cpt Violation , Strings , and Neutral - Meson Systems
Symmetry under the discrete transformation CPT is a general theoretical condition holding for local relativistic field theories of point particles [1]-[7]. This symmetry has been investigated experimentally under different circumstances and to a high degree of precision [8]. The broad theoretical validity of CPT symmetry for particles and the availability of high-precision tests makes CPT viola...
متن کاملGalactic Antiproton and Cpt
Recently, it has been suggested that a signi cant test of CPT invariance can be derived by comparing the proton lifetime ( p > 10 32 years) with the antiproton lifetime p . CPT invariance would require p = p . A deviation from CPT induced by gravity e ects, if linear in the ratio between proton mass (mp) to Planck mass (MP l), could generate a p 5 10 31 M2P l (GeV) years 10 8 years. A precise m...
متن کاملCpt and Superstring *
We discuss the possibility that CPT violation may appear as a consequence of microscopic decoherence due to quantum-gravity effects, that we describe using a density-matrix formalism motivated by our studies of non-critical string theory. The maximum possible order of magnitude of such decohering CPT-violating effects is not far from the sensitivity of present experiments on the neutral kaon sy...
