Experimentalists have measured CP violation in neutral K and B mesons.
Everybody is unhappy that so far there are only 2 systems so
for which these measurements are possible.
(Neutral D mesons are predicted to show such a small effect that it
is probably unmeasurable for a long time.)
All these are spin 0 mesons.
But why is it not possible to test CP violation also in spin 1 mesons,
such as K* and B*? Is there a fundamental reason or is it simply that
experiments are too difficult?
