    "abstract": "We analyze the recently proposed mirror superposition experiment of Marshall,\nSimon, Penrose, and Bouwmeester, assuming that the mirror\u0027s dynamics contains a\nnon-unitary term of the Lindblad type proportional to -[q,[q,\\rho]], with q the\nposition operator for the center of mass of the mirror, and \\rho the\nstatistical operator. We derive an exact formula for the fringe visibility for\nthis system. We discuss the consequences of our result for tests of\nenvironmental decoherence and of collapse models. In particular, we find that\nwith the conventional parameters for the CSL model of state vector collapse,\nmaintenance of coherence is expected to within an accuracy of at least 1 part\nin 10^{8}. Increasing the apparatus coupling to environmental decoherence may\nlead to observable modifications of the fringe visibility, with time dependence\ngiven by our exact result.",
