A natural theory of dark energy
Lorenzo Bordin, Francesc Cunillera, Antoine Lehébel +1
We propose a mechanism that generates a naturally light dark energy field (with Hubble scale mass), starting from a theory with exclusively high scale (Planckian) couplings. It is…
The Super-Stuckelberg procedure and dS in Pure Supergravity
Silvia Nagy, Antonio Padilla, Ivonne Zavala
Understanding de Sitter space in supergravity - and string theory - has lead to an intense amount of work for more than two decades, largely motivated by the discovery of the accel…
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…
Cosmological consequences of Omnia Sequestra
Ben Coltman, Yixuan Li, Antonio Padilla
Vacuum energy sequestering is a mechanism for cancelling off the radiative corrections to vacuum energy. The most comprehensive low energy model, proposed in 1606.04958 [hep-th], h…
