Form factors, spectral and Källén-Lehmann representation in nonlocal quantum gravity
Fabio Briscese, Gianluca Calcagni, Leonardo Modesto +1
We discuss the conical region of convergence of exponential and asymptotically polynomial form factors and their integral representations. Then, we calculate the spectral represent…

Path integral and conformal instability in nonlocal quantum gravity
Gianluca Calcagni, Leonardo Modesto
We introduce the Lorentzian path integral of nonlocal quantum gravity. After introducing the functional measure, the Faddeev-Popov sector and the field correlators, we move to pert…
