The CMB bispectrum without primordial non-Gaussianities
| The Cosmic Microwave Background (CMB) is considered a powerful observational tool to probe the physical processes in the early Universe. In models, based on the traditional treatments within the inflationary paradigm, the bispectrum is seen as an irrefutable proof of non-Gaussian statistics in the primordial perturbations. In this talk, we will show how the proposal of the self-induced collapse of the wave function, which has been introduced in order to address the so-called ``quantum-to-classical'' transition during the inflationary era, naturally leads to a definite prediction regarding the shape and amplitude for the CMB bispectrum without assuming any non-Gaussianities in the primordial perturbations. These predictions can be confronted with the existing observations. |
