Testing kappa-Poincaré with neutral kaons
No full textIn recent work on experimental tests of quantum-gravity-motivated phenomenological models, a significant role has been played by the so-called ``'' deformations of Poincaré symmetries. Sensitivity to values of the relevant deformation length as small as has been achieved in recent analyses comparing the structure of -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 estimate indicates that experiments on the neutral kaons may actually be more already allow to probe values of of order the Planck length.In recent work on experimental tests of quantum-gravity-motivated phenomenological models, a significant role has been played by the so-called ``'' deformations of Poincar\'e symmetries. Sensitivity to values of the relevant deformation length as small as has been achieved in recent analyses comparing the structure of -Poincar\'e symmetries with data on the gamma rays we detect from distant astrophysical sources. We investigate violations of CPT symmetry which may be associated with -Poincar\'e in the physics of the neutral-kaon system. A simple estimate indicates that experiments on the neutral kaons may actually be more -sensitive than corresponding astrophysical experiments, and may already allow to probe values of of order the Planck length
