Abstract
In this paper we will show how “weighted path integral” proposed by Mensky and Kent can emerge out of Ghirardi Rimini Weber (GRW) model.

Notes
Some versions of GRW model subject just one particle to a hit instead of the entire configuration of n particles. In those cases, we would have a single \(\delta \)-function in \(\mathbb {R}^3\) instead of superposition of n such \(\delta \)-function; but this won’t affect the ultimate conclusion that the reality is in \(\mathbb {R}^3\). In any case, as far as this paper is concerned, our assumption is that we subject a configuration of n-particles to simultaneous hit.
This argument has also been made in Section 4 of [7], where we were referring to the previous version of the current paper (arXiv:1305.7516, version 1). I chose to reiterate it in this paper since this is really the bridge between the two papers, equally relevent to both of them.
