Quarks and neutrinos (please correct me if I'm wrong here!) are the only particles known to oscillate from one form (flavour) to another.
Is it possible that they interact? Quarks being static, neutrinos being transient, is it also possible that they exchange information? Hypothetically speaking, of course... I know of no experiments currently tackling it.
I appreciate this is a wild-card kind of question, but it is one I have pondered for a number of years.
