Modified gravity approaches to the cosmological constant problem
The FADE Collaboration, Heliudson Bernardo, Benjamin Bose +5
The cosmological constant and its phenomenology remain among the greatest puzzles in theoretical physics. We review how modifications of Einstein's general relativity could allevia…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Deconstructing higher order clockwork gravity
Anastasios Avgoustidis, Florian Niedermann, Antonio Padilla +1
We consider the higher order clockwork theory of gravitational interactions, whereby a number of gravitons are coupled together with TeV strength, but nevertheless generate a Planc…
Resolving the Hubble Tension with New Early Dark Energy
Florian Niedermann, Martin S. Sloth
New Early Dark Energy (NEDE) is a component of vacuum energy at the electron volt scale, which decays in a first-order phase transition shortly before recombination [arXiv:1910.107…
New Early Dark Energy
Florian Niedermann, Martin S. Sloth
New measurements of the expansion rate of the Universe have plunged the standard model of cosmology into a severe crisis. In this letter, we propose a simple resolution to the prob…
Quantum corrections to vacuum energy sequestering (with monodromy)
Basem Kamal El-Menoufi, Silvia Nagy, Florian Niedermann +1
Field theory models of axion monodromy have been shown to exhibit vacuum energy sequestering as an emergent phenomenon for cancelling radiative corrections to the cosmological cons…
