Beyond Bell's theorem: Admissible hidden-variable models for the spin-singlet

Abstract

Assuming that quantum mechanics is obeyed exactly after averaging over hidden variables, and considering models that obey both the hypotheses of free will and locality, we establish the form of all possible hidden-variable models that reproduce the spin-singlet.

Based on the oral presentation given at DICE 2012, submitted to J. Phys. Conf. Ser. No new results compared to arXiv:1105.1286 [quant-ph], just a different exposition. Reused an appendix reviewing some HV models that was excised in the final version of 1105.1286
