Bayesian inference of CSL-Parameters — •Björn Schrinski and Klaus Hornberger — Fakultät für Physik, Universität Duisburg-Essen, Duisburg

Collapse models [1] are a possible explanation for the absence of quantum mechanical superpositions on macroscopic scales. The most prevalent model is the Continuous Spontaneous Localization (CSL) model [2] being under intensified scrutiny in recent years [3]. While uninformative Bayesian parameter estimation can be applied to assess the degree to which a specific experiment verifies quantum mechanics on macroscopic scales [4], we show here how one can use the Bayesian approach to combine all experimental observations to obtain conservative exclusion regions in the CSL parameter space.
