- W2573166056 abstract "In this work we investigate a inflationary scenario generated by a large scalar field $phi$ that non-minimally couples to a $f(R)$ modified gravity model. For a Starobinsky's like model, it is found that along a particular flat direction, the scalar potential takes a simple form $V = (M_p^4/4) [V(phi)/alpha(phi)^2]$ where $alpha(phi)$ is a non-minimal coupling to Ricci scalar $R$ in the model. The inflation, therefore, is effectively represented as a single field inflaton scenario. For a specific example, such as a scalar potential $V(phi) = mu_1phi^2 + mu_2phi^4$, we found that the predictions match nicely in the $1sigma$ confidence level of textit{Plank} TT, TE, EE+lowP combination data of Planck 2015 CMB data for $ 0<mu_3 leq 100$, where $mu_3 := |mu_1|/(mu_2 M_p^2)$. For example, taking $mu_3 = 0.01$ the scalar-to-tensor ratio $r=0.0004$ and and spectral index $n_s = 0.96985$ for $N_ast = 50$ while taking $mu_3 = 100.0$ produces $r= 0.03$ and $n_s = 0.96359$ for $N_ast = 60$." @default.
