Abstract: The usual phenomenology of the complex formed by a neutral flavoured meson M-0 and its antiparticle (M) over bar (0) assumes the absence of vacuum regeneration in this complex. We propose experiments for determining the two amplitudes of (possibly non-zero) vacuum regeneration: (i) a comparison of the time dependence of decays of the M-0 and (M) over bar (0) into a channel which could be a CP-eigenstate (e-g., pi(+)pi(-) or pi(0)pi(0)pi(0)), or a general channel like pi/nu; (ii) a measurement of the ratio of the time-dependent transmutations, (M-0 --> (M) over bar (0)) and ((M) over bar (0) --> M-0); (iii) a measurement of the ratio of the time-dependent probabilities for the production of \(MM0)-M-0> and \(M) over bar (0)(M) over bar (0)> states, starting with a C-odd correlated \(M) over bar (0)(M) over bar (0)> state like the phi-meson. The proposed experiments are required to be as accurate as those for the known CP-violation effects in the (M-0, (M) over bar (0)) complex.
