  Why do we never see a table in a superposition of here and there? This
problem gets a solution by so called collapse models assuming the collapse as a
genuinely physical process. Here we consider two specific collapse models and
apply them to systems at high energies, i.e. flavour oscillating neutral meson
systems. We find on one hand a potentially new interpretation of the decay
rates introduced by hand in the standard formalism and on the other hand that
these systems at high energies constrain by experimental data the possible
collapse scenarios.
