Leading order effective operators in quantum gravity
Tommaso Antonelli, Xavier Calmet, Stephen D. H. Hsu
We explore the nature of higher dimensional operators generated by quantum gravity. Calculating the tree-level and one-loop effective operators generated by graviton exchange betwe…

The Weak Gravity Conjecture in the Vilkovisky-DeWitt Effective Action of Quantum Gravity
Tommaso Antonelli, Xavier Calmet
The Weak Gravity Conjecture states that in any consistent theory of quantum gravity in the landscape of string theory, the repulsive force mediated by a U(1) gauge field must be st…
