AMELINO-CAMELIA, GIOVANNI BUCCELLA, FRANCO 2011 <jats:p> In recent work on experimental tests of quantum-gravity-motivated phenomenological models, a significant role has been played by the so-called "κ" deformations of Poincaré symmetries. Sensitivity to values of the relevant deformation length λ as small as 5×10<jats:sup>-33</jats:sup> m has been achieved in recent analyses comparing the structure of κ-Poincaré symmetries with data on the gamma rays we detect from distant astrophysical sources. We investigate violations of CPT symmetry which may be associated with κ-Poincaré in the physics of the neutral-kaon system. A simple estimate indicates that experiments on the neutral kaons may actually be more λ-sensitive than the corresponding astrophysical experiments, and may already allow to probe values of λ of order the Planck length. </jats:p> application/pdf https://sonar.ch/global/documents/32661 eng info:eu-repo/semantics/altIdentifier/doi/10.1142/s0217732300002474 info:eu-repo/semantics/altIdentifier/issn/0217-7323 info:eu-repo/semantics/openAccess Modern Physics Letters A. - World Scientific Pub Co Pte Lt. - 2000, vol. 15, no. 34, p. 2119-2127 TESTING κ-POINCARÉ WITH NEUTRAL KAONS http://purl.org/coar/resource_type/c_6501
