WebbWe study an axion inflation model recently proposed within the framework of type IIB superstring theory, where we pay a particular attention to a sub-Planckian axion decay constant. Our axion potential can lead to the small field inflation with a small tensor-to-scalar ratio, and a typical reheating temperature can be as low as GeV. Webb11 aug. 2024 · It is shown that in this class of models the symmetry structure leads to both large and small field inflationary trajectories within a single modular inflation model. The …

Webb22 mars 2024 · For the small field inflation, however, we present the parameter decoupling and coupling scenarios. For both scenarios, we compute and inspect n_s and r showing interesting results. For three different values of the number of e-folds N=60,65 and 70, we find that the coupling between f(R,T)1 and the scalar potential via the moduli space … Webb9 sep. 2011 · We explore some issues in slow roll inflation in situations where field excursions are small compared to Mp.

Note on initial conditions for small-field inflation
Webb1 juni 2012 · We explore some issues in slow roll inflation in situations where field excursions are small compared to M {sub p}. We argue that for small field inflation, minimizing fine tuning requires low energy supersymmetry and a tightly constrained structure. Hybrid inflation is almost an inevitable outcome. WebbWe consider ”new inflation” inflationary models at small fields, embedded in minimal N = 1 supergravity with a single chiral superfield. Imposing a period of inflation compati Webb30 mars 2024 · Long standing themes in inflation include the issue of large field vs. small field inflation as well as the question what fraction of phase space leads to sufficient inflation and furthermore is ... chuck norris game show host
