where the prime denotes the derivative with respect to ψ . By substituting N$_{TI}$ from Eq. (4.58) or Eq. (4.62) into Eq. (4.69) we obtain

where A = 5 6 for Γ$_{ϕ}$ ≳ H$_{TI}$ (Eq. (4.58)) or A = 5 16 for Γ$_{ϕ}$ ≪ H$_{TI}$ (Eq. (4.62)). Then, from our mass definition m , Eq. (4.3), we obtain 

The non-Gaussianity parameter g$_{NL}$ is obtained as [51]
