A speed limit on tachyon fields from cosmological and fine-structure data
J. D. F. Dias, Nils Schöneberg, Léo Vacher +2
The rolling tachyon is a non-canonical scalar field model well motivated in string theory which naturally predicts variations of the fine-structure constant. Such variations can in…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
News from the Swampland -- Constraining string theory with astrophysics and cosmology
Nils Schöneberg, Léo Vacher, J. D. F. Dias +2
Our current best guess for a unified theory of gravitation and quantum field theory (string theory) generically predicts a set of requirements for a consistently quantized theory,…
Runaway dilaton models: improved constraints from the full cosmological evolution
Léo Vacher, Nils Schöneberg, J. D. F. Dias +2
One of the few firm predictions of string theory is the existence of a massless scalar field coupled to gravity, the dilaton. In its presence, the value of the fundamental constant…
Constraints on extended Bekenstein models from cosmological, astrophysical, and local data
Léo Vacher, João F. Dias, Nils Schöneberg +5
Searching for variations of nature's fundamental constants is a crucial step in our quest to go beyond our current standard model of fundamental physics. If they exist, such variat…
