Electroweak relaxation of cosmological hierarchy

  title={Electroweak relaxation of cosmological hierarchy},
  author={Shao-Jiang Wang},
  journal={Physical Review D},
A simple model for the late-time cosmic acceleration problem is presented in the Starobinsky inflation with a negative bare cosmological constant as well as a nonminimal coupling to the Higgs boson. After electroweak symmetry breaking, the Starobinsky inflaton has been frozen until very recently, becoming a thawing quintessence, and a comparable magnitude to the observed dark energy density can be achieved without fine-tuning. Our proposal essentially reduces the cosmological constant problem…

Dark energy without fine tuning
Abstract We present a two-field model that realises inflation and the observed density of dark energy today, whilst solving the fine-tuning problems inherent in quintessence models. One field acts
Dark energy and the refined de sitter conjecture
A bstractWe revisit the phenomenology of quintessence models in light of the recently refined version of the de Sitter Swampland conjecture, which includes the possibility of unstable de Sitter
Higgs potential near-criticality from a de Sitter swampland-like condition
Motivated by the recently proposed de Sitter swampland conjecture, a formally same condition imposed instead on the convex and real exact effective potential is contemplated. Compared to the original

Multi-field inflation in high-slope potentials
We present two families of multi-field potentials that support inflation while satisfying the refined de Sitter and the distance swampland conjectures. Both families feature Planck-compatible
Dark energy beyond quintessence: constraints from the swampland
A bstractThe string theory swampland proposes that there is no UV-completion for an effective field theory with an exact (metastable) de Sitter vacua, thereby ruling out standard ΛCDM cosmology if
Reconstructing Horndeski theories from cosmological observables
The nature of the accelerated expansion of the Universe remains one of the greatest challenges in modern physics. The simplest explanation is that the acceleration is driven by a cosmological
What does inflation say about dark energy given the swampland conjectures?
We discuss the relations between swampland conjectures and observational constraints on both inflation and dark energy. Using the requirement $|\nabla V|\geq c V$, with $c$ as a universal constant
Swampland conjecture in f(R) gravity by the Noether symmetry approach
Swampland conjecture has been recently proposed to connect early time cosmological models with the string landscape, and then to understand if related scalar fields and potentials can come from some
Pixelated Dark Energy
We study the phenomenology of a recent string construction with a quantum mechanically stable dark energy. A mild supersymmetry protects the vacuum energy but also allows O(10−100) TeV scale


Cosmological Relaxation of the Electroweak Scale.
A new class of solutions to the electroweak hierarchy problem is presented that does not require either weak-scale dynamics or anthropics. Dynamical evolution during the early Universe drives the
Dark energy as a remnant of inflation and electroweak symmetry breaking
A bstractIt is shown that dark energy can be obtained from the interplay of the Higgs boson and the inflaton. A key element is the realization that electroweak symmetry breaking can trigger a second

Solving the Hierarchy Problem at Reheating with a Large Number of Degrees of Freedom.
We present a new solution to the electroweak hierarchy problem. We introduce N copies of the standard model with varying values of the Higgs mass parameter. This generically yields a sector whose
Quintessential inflation
We present an explicit observationally acceptable model for evolution from inflation to the present epoch under the assumption that the entropy and matter of the familiar universe are from
Cosmological Aspects of Higgs Vacuum Metastability
The current central experimental values of the parameters of the Standard Model give rise to a striking conclusion: metastability of the electroweak vacuum is favoured over absolute stability. A
The Landscape, the Swampland and the Era of Precision Cosmology
We review the advanced version of the KKLT construction and pure d=4 de Sitter supergravity, involving a nilpotent multiplet, with regard to various conjectures that de Sitter state cannot exist in
Primordial black holes and the string swampland
The "swampland conjectures" have been recently suggested as a set of criteria to assess if effective field theories (EFTs) are consistent with a quantum gravity embedding. Such criteria, which
