Bounds on Spontaneous Collapse model of Quantum Mechanics from formation of CMBR and Standard Cosmology

Continuous Spontaneous Localization (CSL) model of Quantum Mechanics modifies Schr"{o}dinger equation by adding non-linear stochastic terms due to which the total energy of a system increases with a constant rate which is proportional to the collapse rate $\lambda$. Thus applying CSL model to cosmological scenarios can change the thermal behaviour of the particles during evolution and we will put constraints on $\lambda$ by considering several cosmological scenarios.
