Primordial Black Holes from Effective Field Theory of Stochastic Single Field Inflation at NNNLO
Sayantan Choudhury, Ahaskar Karde, Pankaj Padiyar +1
We present a study of the Effective Field Theory (EFT) generalization of stochastic inflation in a model-independent single-field framework and its impact on primordial black hole…
Realisation of the ultra-slow roll phase in Galileon inflation and PBH overproduction
Sayantan Choudhury, Ahaskar Karde, Sudhakar Panda +1
We demonstrate the explicit realisation of the ultra-slow roll phase in the framework of the effective field theory of single-field Galileon inflation. The pulsar timing array (PTA…
Primordial non-Gaussianity as a saviour for PBH overproduction in SIGWs generated by Pulsar Timing Arrays for Galileon inflation
Sayantan Choudhury, Kritartha Dey, Ahaskar Karde +2
We investigate the explicit role of negative local non-Gaussianity, , in suppressing the abundance of primordial black holes (PBHs) in the single-field model of Galileo…
