Are there any experiments that supports de broglie-Bohm theory?

[cryptist]

There are a lot of experiments to disproof hidden variable theories with Bell's inequalities (local) and Leggett's inequalities (non-local). But de broglie-Bohm theory (dBB) survives from all of them. Also I know there is an Quantum Equilibrium Hypothesis says that everything that disproof dBB, will also disproof standard quantum mechanics (SQM).

But, is there any experiment that gives better results on dBB than SQM? Or is there any experiment that supports dBB against SQM?

Isn't this dBB and QM equivalence a bit overestimated? As far as I know, QM does not explain behaviour of many particles states. So, it has been already disproven, since there is certainly more than one particle in the universe. So is dBB.

dBB assumes particles are hard balls, so it is difficult to explain i.e. decay, annihilation or flavour oscillations.

All these difficulties are removed by the dBB interpretation of quantum field theory:

I think that time in QM better fits in the dBB thinking than in the SQM thinking:

Ok, but is there any experiment that distinguishes the difference of dbb and SQM? Or there can be such an experiment?

Well, dBB is richer than SQM in the sense that it allows a POSSIBILITY that a system may be out of quantum equilibrium, i.e., the statistical distribution may differ from |psi|^2. Such a possibility is very unlikely in dBB, but is still possible. So, if one would find a system in which the empirical distribution is not given by |psi|^2, this would contradict SQM, but perhaps could still be explained by dBB.
