Asymptotic Safety: Swampland or Wonderland?

Understand

We investigate the consequences of combining swampland conjectures with the requirement of asymptotic safety.

• To this end, we explore the infrared regime of asymptotically safe gravity in the quadratic one-loop approximation, and we identify the hypersurface spanned by the endpoints of asymptotically safe renormalization group trajectories.
• These comprise the allowed values of higher-derivative couplings as well as standard logarithmic form factors.
• We determine the intersection of this hypersurface with the regions of parameter space allowed by the weak-gravity conjecture, the swampland de Sitter conjecture, and the trans-Planckian censorship conjecture.
