Mesons violate Bell’s inequality
6 November 2003

The famous Bell's inequality of quantum mechanics has been tested in a high-energy particle physics experiment for the first time. The inequality was violated by three standard deviations in experiments with B mesons at the KEK laboratory in Japan - yet again confirming the predictions of quantum theory (arxiv.org/abs/quant-ph/0310192; J. Mod. Optics to be published). Previously most Bell's inequality experiments have been performed with photons or ions.

It's interesting to say the least, though of course it's not yet been reproduced. opinions? wild speculation?

Looks like something that could be repeated with the full Belle dataset, or with the future Belle II dataset. The decay chain is quite common and should have a high trigger efficiency.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
