“…The Planck satellite is unable to measure such a small value of non-Gaussianity. Contrarily, the non-minimal coupled case [13,14] supports Planck-2015 [15] and Planck-2018 [16] released data that suggest a nearly scale-invariant power spectrum with a large non-Gaussian power spectrum ( f NL ? 1).…”

“…There are numerous versions of the inflationary scenario, which basically differ in the form of the scalar field potential causing the inflation. Some of the most frequently employed potentials are exponential potential [36][37][38][39], power-law potential [14,40] and inverse power-law potential [41]. We consider the potential in the following general form…”

“…[15,16]. On the other hand, it has also been exhaustively investigated other different aspects of inflationary cosmology in the presence of non-minimal coupling such as for JCAP08(2019)029 example the phase-space analysis [17,18], slow-roll approximation and conformal transformation techniques [19][20][21], power-law inflation [22][23][24], and non-Gaussianities [25][26][27]. Also, the consequences of general non-minimal couplings for inflation have also been investigated in the framework of scalar-tensor theories, in the so-called extended and hyper-extended inflation [28][29][30][31][32][33][34][35][36].…”

“…To discriminate among the different components that may be responsible for the present acceleration of the universe [74,75], two new geometrical parameters, termed as the statefinder parameters, which depend on the nature of the space-time metric, were introduced by Sahni et al [76]. These parameters are usually denoted by r and s, but here, we will denote them by and .…”
