    "abstract": "We propose that the mechanism responsible for the ``collapse of the wave\nfunction\" (or \"decoherence\" in its broadest meaning) in quantum mechanics is\nthe nonlinearities already present in the theory via nonabelian gauge\ninteractions. Unlike all other models of spontaneous collapse, our proposal is,\nto the best of our knowledge, the only one which does not introduce any new\nelements into the theory. Indeed, unless the gauge interaction nonlinearities\nare not used for exactly this purpose, one must then explain why the violation\nof the superposition principle which they introduce does not destroy quantum\nmechanics. A possible experimental test of the model would be to compare the\ncoherence lengths for, e.g., electrons and photons in a double-slit experiment.\nThe electrons should have a finite coherence length, while photons should have\na much longer (in principle infinite) coherence length.",
