Experimental constrains on the Continuous Spontaneous Localization model from spontaneous radiation emission

Kristian Piscicchia, Angelo Bassi, Catalina Curceanu +3 more

The work presented in this paper aimed to obtain new, more stringent, limits on the parameters of the Continuous Spontaneous Localization collapse model. The result is accomplished by performing a Bayesian analysis of the X-ray emission data collected by the IGEX collaboration, compared with the spontaneous photon emission which is predicted by collapse models. The most stringent limits on the collapse rate $\lambda$ and the correlation length $r_C$ of the CSL model are obtained , with respect to any other method, over a broad range of the parameters space.The work presented in this paper aimed to obtain new, more stringent, limits on the parameters of the Continuous Spontaneous Localization collapse model.
