Chaotic G-Inflation Consistent With Observations

29 Aug 2018  ·  Güleryüz Ömer ·

We examine the Galileon-like inflation model G-Inflation with minimal coupling where the inflaton potential is Chaotic inflation potential. In addition we examine, how the non-minimal coupling with chosen non-zero vacuum expectation values $v$ after inflation and varying non-minimal coupling constant values $\xi$ affects and changes the predictions and when the Galileon term dominates the inflation... We have constructed a valid model of chaotic inflation which is chaotic G-Inflation, showing that the observational parameters tensor-to-scalar ratio and spectral indices are comparable and consistent with current observations. read more
