D. Predictions for neutral-meson interferometry from L SME , extract CPT-violating Hamiltonian contribution d H SME for valence quarks of meson P 0 = K 0 , D 0 , B 0 d , B 0 s under consideration usual quantum perturbation theory in meson rest


  1. D. Predictions for neutral-meson interferometry from L SME , extract CPT-violating Hamiltonian contribution d H SME for valence quarks of meson P 0 = K 0 , D 0 , B 0 d , B 0 s under consideration usual quantum perturbation theory in meson rest frame: symmetry considerations, Hermiticity of d H SME , and boosting yield: b m … 4-velocity of meson in observer frame a m … Lorentz-/CPT-violating SME parameter for valence quark

  2. → phenomenological d K can be calculated within SME: … usual superweak angle … boost factor from kaon speed b Notice: - kaon direction is essential exp. parameter, as expected → 4 p averaging may remove any CPT-violating signals - larger kaon speeds tend to enhance CPT-violating effects → this gives possibilities to increase CPT reach Remark: meson interferometry is the only known class of tests probing a m -type SME coefficients
