Generic no-scale inflation inspired from string theory compactifications

We propose the generic no-scale inflation inspired from string theory compactifications. consider K\"ahler potentials with an inflaton field $\ensuremath{\varphi}$, as well one, two, and three moduli. Also, we renormalizable superpotential of $\ensuremath{\varphi}$ in general. study spectral index tensor-to-scalar ratio details, find viable parameter spaces which are consistent Planck BICEP/Keck experimental data on cosmic microwave background (CMB). The is ${n}_{s}\ensuremath{\simeq}1\ensuremath{-}2/N\ensuremath{\sim}0.965$ for all models, $r$ $r\ensuremath{\simeq}12/{N}^{2}$, $83/{N}^{4}$ $4/{N}^{2}$ two moduli respectively. particular model comes contributions non-negligible higher order term potential. In model, scalar potential similar to global supersymmetry, but different. E $\ensuremath{\alpha}=1$ T $\ensuremath{\alpha}=1/3$ can be realized one modulus Interestingly, models quadratic quartic still satisfy current tight bound after embedding into supergravity.
