    "abstract": "A local hidden variable model exploiting the detection loophole to reproduce\nexactly the quantum correlation of the singlet state is presented. The model is\nshown to be compatible with both the CHSH and the CH Bell inequalities.\nMoreover, it bears the same rotational symmetry as spins. The reason why the\nmodel can reproduce the quantum correlation without violating the Bell theorem\nis that in the model the efficiency of the detectors depends on the local\nhidden variable. On average the detector efficiency is limited to 75%.",
