The swampland conjecture and the Higgs expectation value
TLDR
In this article, it was shown that a modified Higgs potential generically results in a $Q$-dependent Higgs vacuum expectation value (VEV), which is severely excluded by the tests of the equivalence principle.Abstract:
The recently proposed de Sitter swampland conjecture excludes local extrema of a scalar potential with a positive energy density in a low energy effective theory. Under the conjecture, the observed dark energy cannot be explained by the cosmological constant. The local maximum of the Higgs potential at the symmetric point also contradicts with the conjecture. In order to make the Standard Model consistent with the conjecture, it has been proposed to introduce a quintessence field, $Q$, which couples to the cosmological constant and the local maximum of the Higgs potential. In this paper, we show that such a modified Higgs potential generically results in a $Q$-dependent Higgs vacuum expectation value (VEV). The $Q$-dependence of the Higgs VEV induces a long-range force, which is severely excluded by the tests of the equivalence principle. Besides, as the quintessence field is in motion, the Higgs VEV shows a time-dependence, which is also severely constrained by the measurements of the time-dependence of the proton-to-electron mass ratio. Those constraints require an additional fine-tuning which is justified neither by the swampland conjecture nor the anthropic principle. We further show that, even if such an unjustified fine-tuning condition is imposed at the tree level, radiative corrections upset it. Consequently, we argue that most of the habitable vacua in the string landscape are in tension with the phenomenological constraints.read more

The Swampland: Introduction and Review
TL;DR: The Swampland program aims to distinguish effective theories which can be completed into quantum gravity in the ultraviolet from those which cannot as mentioned in this paper, assuming only a knowledge of quantum field theory and general relativity.

The Asymptotic dS Swampland Conjecture ‐ a Simplified Derivation and a Potential Loophole

TL;DR: In this paper, a simpler way to reach a simpler conclusion is to consider potentials which, while they remain below an exponentially falling bound, have small oscillations leading locally to relatively flat regions or even to an infinite series of dS minima.

Steep eternal inflation and the swampland
TL;DR: In this paper, the authors investigated whether eternal inflation is possible when the inflaton originally travels up the scalar potential and inevitably reaches a turnaround point where its classical kinetic energy momentarily vanishes.

TL;DR: It is argued that a number of models in which the energy density of the scalar field red-shifts in a specific manner are studied could reconcile the low dynamical estimates of the mean mass density with the negligibly small spatial curvature preferred by inflation.
