Abstract: (Damghan University)

In this paper, we are going to investigate a new perspective of the two-field inflationmodel with respect to the swampland dS conjecture. At the first step, we study the two-fieldsinflation model, and apply the swampland conjecture to our model. Then, we calculate somecosmological parameters such as scalar spectrum index, tensor-to-scalar ratio, and compare ourresults with the recent observational data. Also, we give numerical analysis to show agreementwith observational data.
