Non-minimal coupled warm inflation with quantum-corrected self-interacting inflaton potential

Abstract

Abstract In this work, we investigate the non-minimally coupled scenario in the context of warm inflation with quantum-corrected self-interacting potential. We transform the potential in the Jordan frame to the Einstein frame and consider a dissipation parameter of the form $$\Gamma = C_{T}T$$ Γ = C T T with $$C_T$$ C T being a coupling parameter. We focus on the strong regime of which the interaction between inflaton and radiation fluid has been taken into account. We compute inflationary observables and constrain the parameters of our model using current Planck 2018 data. With the sizeable number of e-folds and proper choices of parameters, we discover that allowed values of $$C_T$$ C T lie in the range $$0.014\lesssim C_{T}\lesssim 0.020$$ 0.014 ≲ C T ≲ 0.020 in which the predictions are in good agreement with the latest Planck 2018 results at the $$2\,\sigma $$ 2 σ confident level.
