Bondi Four-Momentum Balance in Quantum NSF Classical matching, DKL supermomentum, and quantum energy redistribution
Carlos Kozameh, Gerardo DEpaola
We derive Bondi four-momentum balance between past and future null infinity in the radiative phase space of the null-surface formulation (NSF). Weyl matching at spatial infinity, t…
Ultraviolet-Finite Perturbative Expansion of Quantum Gravity at Null Infinity
Carlos N. Kozameh, Gerardo O. Depaola
We present a perturbative formulation of quantum gravity for asymptotically flat vacuum spacetimes based on the Null Surface Formulation (NSF), in which the expansion is ultraviole…
Quantum graviton scattering with definite helicities in the null surface formulation. III: Fourth-order recursion and ultraviolet finiteness
C. N. Kozameh, G. O. Depaola
We extend the perturbative null-surface formulation (NSF) scattering map to fourth order and derive an all-order recursion for the quantum cut. After the antipodal matching, both c…
Quantum graviton scattering with definite helicities in the null surface formulation, Part II: Third-order scattering and the exchange channels \author{C.~N.~Kozameh \and G.~O.~Depaola}
Carlos Kozameh, Gerardo Depaola
We derive the graviton scattering map in the null-surface formulation (NSF) through third order in perturbations of Minkowski spacetime. The rational structure of the exact NSF equ…
Quantum graviton scattering with definite helicities in the null surface formulation
Carlos Kozameh, Gerardo Depaola
We develop a helicity-resolved description of quantum graviton scattering in the Null Surface Formulation (NSF) of gravity. Dynamical data are Bondi shear modes at null infinity ($…
