    "abstract": "A new derivation of quantum stochastic differential equation for the\nevolution operator in the low density limit is presented. We use the\ndistribution approach and derive a new algebra for quadratic master fields in\nthe low density limit by using the energy representation. We formulate the\nstochastic golden rule in the low density limit case for a system coupling with\nBose field via quadratic interaction. In particular the vacuum expectation\nvalue of the evolution operator is computed and its exponential decay is shown.",
