Description

Scattering amplitudes in non-local and higher derivative theory

Nonlocal and higher derivative field theories allow us to formulate a quantum renormalizable theory of the gravitational field, thanks to an improved ultraviolet convergence of the propagators. In this talk, I will describe the main features of these models, such as renormalizability, Lorentz invariance and quantum unitarity.
