Resumen:
 In the two correlated $B$ meson decay experiment we propose to measure intensities relating CP eigenstate ($J/psi K_{S,L}$) decays on $both$ sides, which will be measurable in future upgrades of KEK and PEP. As a CP-forbidden transition, we obtain $I(J/psi K_S, J/psi K_S, Delta t) sim sin ^2 (2eta)$. We calculate in a model independent way all the possible intensities relating final CP and flavour eigenstate decays. Under CPT-invariance, the asymmetries for processes related by CP$Delta t$ vanish for $Delta Gamma =0$ and measure $Delta Gamma$ linearly. We notice the impossibility to isolate the sign of $cos (2et a)$ without an independent knowledge of the sign of $Delta Gamma$. This exhaustion of the possible Golden Plate and flavour decays provides new observables which may throw light in our present understanding of CKM physics.
