Renormalization of composite operators in $2+\varepsilon$ quantum gravity

By Riccardo Martini

Appears in collection : 2023 - T1A - WS1 - Quantum gravity and random geometry

We consider higher derivative composite operators in the $\varepsilon$-expansion of 2d quantum gravity and renormalize them at one-loop. We extract the flow of the essential couplings and study their analytic continuation in the background dimensions to compare with Stelle gravity in $d=4$.
