Semiclassical interpretation of microscopic processes

There are three upper limits (2, 2.sqrt{2}, 2.sqrt{3}) of the Bell operator corresponding to different physical concepts: classical, hidden-variable and quantum-mechanical. Only the classical concept corresponding to the lowest limit has been excluded by experimental data, while the other two should be regarded as acceptable for the interpretation of EPR experiments and all microscopic processes. A corresponding hidden-variable or semiclassical model (based on the extended Hilbert space) will be proposed and shortly described.
