Query: On signatures of spontaneous collapse dynamics modified single field
  inflation   The observed classicality of primordial perturbations, despite their quantum
origin during inflation, calls for a mechanism for quantum-to-classical
transition of these initial fluctuations. As literature suggests a number of
plausible mechanisms which try to address this issue, it is of importance to
seek for concrete observational signatures of these several approaches in order
to have a better understanding of the early universe dynamics. Among these
several approaches, it is the spontaneous collapse dynamics of Quantum
Mechanics which is most viable of leaving discrete observational signatures as
collapse mechanism inherently changes the generic Quantum dynamics. We observe
in this study that the observables from the scalar sector, i.e. scalar tilt
$n_s$, running of scalar tilt $\alpha_s$ and running of running of scalar tilt
$\beta_s$, can not potentially distinguish a collapse modified inflationary
dynamics in the realm of canonical scalar field and $k-$inflationary scenarios.
The only distinguishable imprint of collapse mechanism lies in the observables
of tensor sector in the form of modified consistency relation and a blue-tilted
tensor spectrum only when the collapse parameter $\delta$ is non-zero and
positive.
