چکیده
A violation of Local Lorentz Invariance (VLI) and hence the special theory of rel-ativity or a violation of equivalence principle (VEP) in the Kaon system can, in principle , induce oscillations between K 0 and ¯ K 0. We construct a general formulation in which simultaneous pairwise diagonalization of mass, momemtum, weak or gravi-tational eigenstates is not assumed. We discuss this problem in a general way and point out that, as expected, the VEP and VLI contributions are indistinguishable. We then insist on the fact that VEP or VLI can occur even when CPT is conserved. A possible CP violation of the superweak type induced by VEP or VLI is introduced and discussed. We show that the general VEP mechanism (or the VLI mechanism, but not both simultaneously), with or without conserved CPT, could be clearly tested experimentally through the energy dependence of the K L − K S mass difference and of η +− , η 00 , δ. Constraints imposed by present experiments are calculated.

A violation of the equivalence principle (VEP) in the Kaon system can, in principle , induce oscillations between K • and K • in a manner that need not violate CPT conservation. We show that such a CPT-conserved VEP mechanism could be clearly tested experimentally through the energy dependence of the K L − K S mass difference and discuss constraints imposed by present experiments.

The maximal acceleration corrections to the Lamb shift of one– electron atoms are calculated in a non–relativistic approximation. They are compatible with experimental results, are in particularly good agreement with the 2S − 2P Lamb shift in hydrogen and reduce by ∼ 50% the experiment-theory discrepancy for the 2S − 2P shift in He. PACS: 04.90.+e, 12.20.Ds.
