Form factors, spectral and Källén-Lehmann representation in nonlocal quantum gravity
Abstract We discuss the conical region of convergence of exponential and asymptotically polynomial form factors and their integral representations. Then, we calculate the spectral representation of the propagator of nonlocal theories with entire form factors, in particular, of the above type. The sp...
