Note on the bispectrum and one-loop corrections in single-field inflation with primordial black hole formation
Jason Kristiano, Jun'ichi Yokoyama
Primordial black holes can be formed from the collapse of large-amplitude perturbation on small scales in the early Universe. Such an enhanced spectrum can be realized by introduci…

Constraining Primordial Black Hole Formation from Single-Field Inflation
Jason Kristiano, Jun'ichi Yokoyama
The most widely studied formation mechanism of a primordial black hole is collapse of large-amplitude perturbation on small scales generated in single-field inflation. In this Lett…
