| Popis: | An alternative refined de Sitter conjecture giving rise to a natural combination of the first and second derivatives of the scalar potential was proposed recently by David Andriot and Christoph Roupec (Fortsch. Phys. 67 (2019) no.1-2, 1800105). In this work, we study the inflation models in a general scalar-tensor theory with exponential and hyperbolic tangent forms of potential as well as model with quantum corrected potential and examine whether these three models of inflation can satisfy this further refining de Sitter swampland conjecture or not. Regarding our analysis with proper choices of parameters with proper choices of parameters $a,b=1-a$ and $q$, we find that these three inflationary models can always satisfy this new refined swampland conjecture. Therefore, all three inflationary models might all be in landscape since the further refining de Sitter swampland conjecture is satisfied. v3: 15 pages, no figure, version accepted by Fortschritte der Physik. arXiv admin note: text overlap with arXiv:2112.14571 by other authors |
