The state matrix ρ for an open quantum system with Markovian evolution obeys a master equation. The master equation evolution can be unraveled into stochastic nonlinear trajectories for a pure state P, such that on average P reproduces ρ. Here we give for the first time a complete parameterization of all diffusive unravelings (in which P evolves continuously but non-differentiably in time). We give...
We analysed the binomial multiplicity moments of the neutral pions, using an extension of the generating functional technique for detection losses. We applied this model-independent method to the individual γ weights of 10000 events of π - p interactions at 40 GeV/c. We compared the obtained results to those of 250 GeV/c. We used the FRITIOF and a shifted KW distribution to describe the data.
