Abstract
The usual phenomenology of the complex formed by
a neutral flavoured meson
M0 and its
antiparticle
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
M0 and
into a channel which
could be a
CP-eigenstate (e.g.,
or
), or a general channel like
; (ii) a measurement of the ratio of
the time-dependent transmutations,
and
; (iii) a measurement of
the ratio of the time-dependent probabilities for
the production of
and
states, starting with a
C-odd
correlated
state like
the
-meson. The proposed experiments are
required to be as accurate as those for the known
CP-violation effects in the
complex.
