usual quantum perturbation theory in meson rest frame: from L SME , extract CPT-violating Hamiltonian contribution dHSME for valence quarks of meson P0 = K0, D0, B0d , B0s under consideration symmetry considerations, Hermiticity of dHSME , and boosting yield:

b m … 4-velocity of meson in observer frame a m … Lorentz-/CPT-violating SME parameter for valence quark

→ phenomenological dK can be calculated within SME: … usual superweak angle … boost factor from kaon speed b Notice: - kaon direction is essential exp. parameter, as expected → 4p 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
