The fermion sector of the SMEFT from asymptotically safe gravity
Astrid Eichhorn, Moritz Gessner, Shouryya Ray
Quantum gravity impacts Standard Model fields through effective interactions generated by renormalization. These appear as Standard Model Effective Field Theory (SMEFT) operators,…
Crossing the desert: Towards predictions for SMEFT coefficients from quantum gravity
Lydia Brenner, Abhishek Chikkaballi, Astrid Eichhorn +1
The SMEFT provides a general framework to search for new physics beyond the current reach of direct detection. One such form of new physics is quantum gravity. Based on dimensional…
A non-local way around the no-global-symmetries conjecture in quantum gravity?
Johanna Borissova, Astrid Eichhorn, Shouryya Ray
The no-global-symmetries conjecture is central to the swampland program that delineates the boundary between effective field theories that can be obtained from a quantum theory of…
The principled-parameterized approach to gravitational collapse
Héloïse Delaporte, Astrid Eichhorn
New physics beyond General Relativity impacts black-hole spacetimes. The effects of new physics can be investigated in a largely theory-agnostic way by following the principled-par…
