Bell violation in primordial cosmology

Understand

In this paper, we have worked on the possibility of setting up an Bell's inequality violating experiment in the context of primordial cosmology following the fundamental principles of quantum mechanics.

• To set up this proposal we have introduced a model independent theoretical framework using which we have studied the creation of new massive particles for the scalar fluctuations in the presence of additional time dependent mass parameter.
• Next we explicitly computed the one point and two point correlation functions from this setup.
• Then we comment on the measurement techniques of isospin breaking interactions of newly introduced massive particles and its further prospects.
