Abstract

Models of dynamical wave function collapse consistently describe the breakdown of the quantum superposition with the growing mass of the system by introducing non-linear and stochas-tic modifications to the standard Schrodinger dynamics. Among them, Continuous Spontaneous Localization (CSL) was extensively investigated both theoretically and experimentally. Measurable consequences of the collapse phenomenon depend on different combinations of the phenomeno-logical parameters of the model-the strength lambda and the correlation length r(C)-and have led, so far, to the exclusion of regions of the admissible (lambda - r(C)) parameters space. We developed a novel approach to disentangle the lambda and r(C) probability density functions, which discloses a more profound statistical insight.
