Query: Inflation in f(R,T) gravity with Double-Well potential   In this piece of work, we studied the inflation in the context of f(R,T)
theory of gravity. We assumed the functional form of f(R,T) to be $R+ \lambda
T$, where R is the Ricci scalar, T is the trace of the Energy-Momentum tensor
and $\lambda$ is the model parameter. The cosmological observable parameters
like scalar spectral index $n_s$ and tensor-to-scalar ratio $r$ are estimated
for Double-Well potential. We found that for $\lambda = 115$, $n_s$ and $r$ are
in good agreement with PLANCK 2018 data. Further, considering the vacuum
expectation value in Double-Well potential to be Planckian, we observed the
admissible range of model parameter to be $101 < \lambda < 130$ for which this
model remains consistent with PLANCK 2018 data.
