# One-loop correction to the enhanced curvature perturbation with local-type non-Gaussianity for the formation of primordial black holes

@article{Meng2022OneloopCT, title={One-loop correction to the enhanced curvature perturbation with local-type non-Gaussianity for the formation of primordial black holes}, author={De-Shuang Meng and Chengchao Yuan and Qing Guo Huang}, journal={Physical Review D}, year={2022} }

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…
