Confronting K\"ahler moduli inflation with CMB data
  In models of inflation obtained from string compactification, moduli vacuum
misalignment leads to an epoch in the post-inflationary history of the universe
when the energy density is dominated by cold moduli particles. This effect
leads to a modification in the number of $e$-foldings ($N_{\rm pivot}$) between
horizon exit of the CMB modes and the end of inflation. Taking K\"ahler moduli
inflation as a prototype, the shift in $e$-foldings turns out to be a function
of the model parameters which also determines the inflationary observables. We
analyse this scenario numerically using publicly available {\sc{ModeChord}} and
{\sc{CosmoMC}} with the latest \emph{Planck+BICEP2/Keck array} data to
constrain the model parameters and $N_{\rm pivot}$. In light of the present and
future precision data, the results show the importance of careful consideration
of any post-inflationary non-standard epoch, as well as of the effects of
reheating.
