  The primordial bispectrum has been considered in the past decade as a
powerful probe of the physical processes taking place in the early Universe.
Within the inflationary paradigm, the properties of the bispectrum are one of
the keys that serves to discriminate among competing scenarios concerning the
details of the origin of cosmological perturbations. However, all of the
scenarios, based on the conventional approach to the so-called
"quantum-to-classical transition" during inflation, lack the ability to point
out the precise physical mechanism responsible for generating the inhomogeneity
and anisotropy of our Universe starting from and exactly homogeneous and
isotropic vacuum state associated with the early inflationary regime. In past
works, we have shown that the proposals involving a spontaneous dynamical
reduction of the quantum state provide plausible explanations for the birth of
said primordial inhomogeneities and anisotropies. In the present letter, we
show that, when considering single-field slow-roll inflation within the context
of such proposals, the expected characteristics of the bispectrum turn out to
be quite different from those found in the traditional approach. In particular,
the statistical features corresponding to the primordial perturbations, which
are normally associated with the bispectrum, are treated here in a novel way
leading to rather different conclusions.
