Title: Inflationary Primordial Black Holes as All Dark Matter,
Abstract: Following a new microlensing constraint on primordial black holes (PBHs) with
$\sim10^{20}$--$10^{28}\,\mathrm{g}$~[1], we revisit the idea of PBH as all
Dark Matter (DM). We have shown that the updated observational constraints
suggest the viable mass function for PBHs as all DM to have a peak at $\simeq
10^{20}\,\mathrm{g}$ with a small width $\sigma \lesssim 0.1$, by imposing
observational constraints on an extended mass function in a proper way. We have
also provided an inflation model that successfully generates PBHs as all DM
fulfilling this requirement.
