Abstract
In this article we present a local hidden variables model for all experimen ts involving photon pairs produced in parametric down conversion, based on the Wigner representation of the radiation field. A modification of the sta ndard quantum theory of detection is made in order to give a local realisti c explanation of the counting rates in photodetectors. This model involves the existence of a real zeropoint field, such that the vacumm level of radi ation lies below the threshold of the detectors.
