  1. 71. Testing foundations of quantum mechanics in the neutral K-meson system
    Dr Beatrix C. Hiesmayr (• Research Center for Quantum Information, Institute of Physics, Slovak Academy of Sciences)

    CPT symmetry, decoherence, Lorentz symmetry breaking
    The high performance detector KLOE at the upgraded DAPHNE machine allows not only for precision measurements to test very fundamental questions in Particle Physics but as well to test foundations of quantum mechanics itself (G. Amelino-Camelia et al, Physics with the KLOE-2 experiment at the upgraded DAPHNE. Europ. Phys. J. C 68, No. 3-4, 619, 2010). In this talk I will show how the neutral...

  2. 0. Status and prospects for Lorentz and CPT violation tests at KLOE and KLOE-2
    Dr Antonio De Santis (INFN Roma1)
    07/12/2010, 15:25
    CPT symmetry, decoherence, Lorentz symmetry breaking
    The neutral kaon system offers a unique possibility to perform fundamental tests of CPT invariance. In this contribution the status and prospects of the KLOE experiment for the tests of CPT and Lorentz symmetries in the context of the Standard Model Extension are presented. A new analysis method is described in detail with the perspective given by the KLOE-2 data-taking campaign.

  3. 60. Search for Lorentz Violation in a Short-Range Gravity Experiment
    Mr Joshua Long (Indiana University)
    07/12/2010, 15:50
    CPT symmetry, decoherence, Lorentz symmetry breaking
    We report on the progress of a continuing experiment designed to be sensitive to gravity and possible new forces in nature at length scales below 50 microns. The experiment uses 1 kHz mechanical oscillators as test masses with a stiff conducting shield between them to suppress backgrounds, a technique that has demonstrated the capability to probe exceptionally small distances using large...

  4. 14. Measurement of the ground-state hyperfine splitting of antihydrogen
    Dr Bertalan Juhasz (Stefan Meyer Institute for Subatomic Physics, Vienna, Austria)
    07/12/2010, 16:15
    CPT symmetry, decoherence, Lorentz symmetry breaking
    The ground-state hyperfine splitting (GS-HFS) of hydrogen at 1.42 GHz has been measured with an extremely high precision of 10^-12. Thus measuring the GS-HFS of antihydrogen, the antimatter counterpart of hydrogen, would be a stringent test of the CPT symmetry. The ASACUSA collaboration at CERN's Antiproton Decelerator (AD) is preparing such an experiment using an atomic beam apparatus [1,2]...
