Description

The BABAR experiment shows that the flavor-tagged Δt distribution of $B^0\to J/\Psi K^0_L$ agrees with the theoretical prediction, but that of $\bar B^0\to J/\Psi \bar K^0$ shows discrepancy at large |Δt| region[1]. The difference could appear from the presence of tree diagrams of $\bar B^0\to \bar K^0_L J/\Psi$ but absence corresponding tree diagram of $B^0\to K^0_L J/\Psi$, in the Cartan's supersymmetry[2]. The tree diagram could contain retarded time effect before $J/\Psi$ creation during propagation of the W boson. The model can be extended to the decay of $B^0\to K^+\pi^-$ and $\bar B^0\to K^-\pi^+$[3], and $B^0\to D^{*-}X\ell^+\nu$[4]. The $Z_3$ symmetry of leptons and quarks[5] suggests that CP violation effects in the $B^0\to D^{*-}X\ell^+\nu$ cannot be detected by our electromagnetic detectors. Possibility of detecting the retarded time effect by rapidly moving the detector[6] will be discussed. [1] B. Aubert et al., (BABAR Collaboration) . Rev. D $\bf{79}$,(2009) 072009.
