# Lyth Bound, eternal inflation and future cosmological missions

@article{Marco2017LythBE, title={Lyth Bound, eternal inflation and future cosmological missions}, author={Alessandro Di Marco}, journal={Physical Review D}, year={2017}, volume={96}, pages={023511} }

In this paper we provide a new expression for the variation of the inflaton field $\Delta\phi$ during the horizon crossing epoch in the context of single field slow roll inflationary models. Such an expression represents a generalization of the well-know Lyth bound. We also explore the consequences of a detection of permille order of the tensor-to-scalar ratio amplitude, $r$, as well as an improvement on the estimation of the scalar spectral index, $n_s$ and its running $\alpha_s$, by the…

To satisfy the swampland criteria, we consider the brane inflation with potential $V(\phi)=\alpha \phi^n\rm{exp}(-\beta^m \phi^m)$, which can be obtained in supergravity inflation model with a small…

We derive an extended version of the well-known Lyth Bound on the total variation of the inflaton field, incorporating higher-order corrections in slow roll. We connect the field variation Δ to both…

The Lyth bound revisited

We investigate the Lyth bound relating the tensor–scalar ratio, r, to the variation of the inflaton field, Δ, over the course of inflation. For inflationary models that produce at least 55 e-folds of…

We study to what extent the spectral index ns and the tensor-to-scalar ratio r determine the field excursion Delta phi during inflation. We analyse the possible degeneracy of Delta phi by comparing…

Lyth bound of inflation with a tilt

We provide strong evidence for universality of the inflationary field range: given an accurate measurement of (n(s), r), one can infer Delta phi in a model-independent way in the sub-Planckian regime…

We explore the consequences of a detection of primordial tensor fluctuations for general single-field models of inflation. Using the effective theory of inflation, we propose a generalization of the…

A pure gravity inflationary model for the Universe is examined which is based on adding an Epsilon term to the usual gravitational Lagrangian, and it is shown that this model gives significant inflation essentially independent of initial conditions.

According to the famous Lyth bound, one can confirm large field inflation by finding tensor modes with sufficiently large tensor-to-scalar ratio $r$. Here we will try to answer two related questions:…
