    "abstract": "In this article we present a local hidden variables model for all experiments\ninvolving photon pairs produced in parametric down conversion, based on the\nWigner representation of the radiation field. A modification of the standard\nquantum theory of detection is made in order to give a local realist\nexplanation of the counting rates in photodetectors. This model involves the\nexistence of a real zeropoint field, such that the vacumm level of radiation\nlies below the threshold of the detectors.",
