4D de Sitter from String Theory via 6D Supergravity
C. P. Burgess, F. Muia, F. Quevedo
We obtain de Sitter (dS) solutions from controlled string-theory constructions. We review how minimal gauged chiral 6D supergravity evades standard dS no-go theorems by having a po…
Quantum Transitions, Detailed Balance, Black Holes and Nothingness
Sebastian Cespedes, Senarath de Alwis, Francesco Muia +1
We consider vacuum transitions by bubble nucleation among 4D vacua with different values and signs of the cosmological constant , including both up and down tunnelings. Followin…
Density Perturbations and Primordial Non-Gaussianities in a Closed Universe
Sebastian Cespedes, Senarath de Alwis, Francesco Muia +1
The spatial curvature of the universe is not yet known. Even though at present the Universe is very close to being essentially flat and most signatures of curvature appear to have…
Light Higgsino Dark Matter from Non-thermal Cosmology
Luis Aparicio, Michele Cicoli, Bhaskar Dutta +2
We study the scenario of higgsino dark matter in the context of a non-standard cosmology with a period of matter-domination prior to Big-Bang nucleosynthesis. Matter-domination cha…
