Gravity, energy conservation and parameter values in collapse models

Abstract

We interpret the probability rule of the CSL collapse theory to mean that the scalar field which causes collapse is the grvitational curvature scalar with two sources, the expectation value of the mass density and a white noise fluctuating source. We examine two models of the fluctuating source, monopole fluctuations and dipole fluctuations, and show that these correspond to two well known collapse models. We relate the two GRW parameters of CSL to fundamental constants, and explain the energy increase as arising from the loss of vacuum gravitational energy. It is shown how a problem with semi-classical grvity may be cured when it is combined with a CSL collapse model.
