As one of the promising candidates of cold dark matter (DM), primordial black holes (PBHs) were formed due to the collapse of over-densed regions generated by the enhanced curvature perturbations during the radiation-dominated era. The enhanced curvature perturbations are expected to be non-Gaussian in some relevant inflation models and hence the higher-order loop corrections to the curvature power spectrum might be non-negligible as well as altering the abundance of PBHs. In this paper, we…

No-go for the formation of heavy mass Primordial Black Holes in Single Field Inflation

We examine the possibility of Primordial Black Holes (PBHs) formation in single field models of inflation. We show that a one-loop correction to the renormalized primordial power spectrum rules out the

Highly non-Gaussian tails and primordial black holes from single-field inflation

For primordial perturbations, deviations from Gaussian statistics on the tail of the probability distribution can be associated with non-perturbative effects of inflation. In this paper, we present

Bayesian implications for the primordial black holes from NANOGrav's pulsar-timing data by using the scalar induced gravitational waves

The constraints on the fraction of the Universe that may have gone into primordial black holes (PBHs) over the mass range 10−5 to 1050 g are updated and even if PBHs make a small contribution to the DM, they could play an important cosmological role and provide a unique probe of the early Universe.
