Primordial non-Gaussianity in noncanonical warm inflation: three- and four-point correlations

Xiao-Min Zhang, Hong-Yang Ma, Peng-Cheng Chu +1

Non-Gaussianity generated in inflation can be contributed by two parts. The first part, denoted by $f_{NL}^{\delta N}$, is the contribution from four-point correlation of inflaton field…
