Observable consequences of a hypothetical transient deviation from   Quantum Mechanics
  The conflict between Quantum Mechanics (QM) and the intuitive concepts of Locality and Realism (LR) is manifest in the correlation between measurements performed in remote regions of a spatially spread entangled state. In this paper, it is hypothesized that transient deviations (from the values predicted by QM) occur if the correlation is measured in a time shorter than L/c, where L is the spatial spread of the entangled state and c is the speed of light. In this way, the conflict is solved by changing QM minimally. Under general assumptions, it is obtained a mathematical model of the process that reproduces the QM value after a time longer than L/c has elapsed. One of the predictions of this model is that oscillations of the rate of coincidences should exist, with a main frequency lower than c/4L. An experiment able to reveal these oscillations is shown to be accessible, by placing stations at about 5 Km and reaching a coincidence rate about 3E5 1/s (a value already obtained at the laboratory scale). This means a test of QM vs LR of a completely new type, with several practical and theoretical advantages.
