A Proof of the Axion?
Gia Dvali, Cesar Gomez, Sebastian Zell
We show that the de Sitter quantum breaking bound when applied to QCD exposes the necessity of the axion solution to the strong CP problem. The Peccei-Quinn mechanism emerges as a…
Discrete Symmetries Excluded by Quantum Breaking
Gia Dvali, Cesar Gomez, Sebastian Zell
In this note we show that the cosmological domain wall and the de Sitter quantum breaking problems complement each other in theories with discrete symmetries that are spontaneously…
Quantum Breaking Bound on de Sitter and Swampland
Gia Dvali, Cesar Gomez, Sebastian Zell
Quantum consistency suggests that any de Sitter patch that lasts a number of Hubble times that exceeds its Gibbons-Hawking entropy divided by the number of light particle species s…
The Scales of the Infrared
Cesar Gomez, Raoul Letschka, Sebastian Zell
In theories with long-range forces like QED or perturbative gravity, loop corrections lead to vanishing amplitudes. There are two well-known procedures to address these infrared di…
