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 ($…

About electrons and position in Triplet Production: some remarks
G. O. Depaola, M. L. Iparraguirre D. Palacios
Taking into account the increasing interest in measuring high energy gamma ray polarization, Boldishev et. at. \cite{[Boldy]} published an extensive and very comprehensive work on…
A Pair Production Telescope for Medium-Energy Gamma-Ray Polarimetry
Stanley D. Hunter, Peter F. Bloser, Gerardo O. Depaola +10
We describe the science motivation and development of a pair production telescope for medium-energy gamma-ray polarimetry. Our instrument concept, the Advanced Energetic Pair Teles…

A Concept for a High-Energy Gamma-ray Polarimeter
P. F. Bloser, S. D. Hunter, G. O. Depaola +1
We present a concept for an imaging gamma-ray polarimeter operating from ~50 MeV to ~1 GeV. Such an instrument would be valuable for the study of high-energy pulsars, active galact…
A method to determine the polarization of high energy gamma-rays
Gerardo O. Depaola, Carlos N. Kozameh, Manuel H. Tiglio
A method to determine the polarization direction of a very high energy (50 MeV - 30 GeV), linearly polarized gamma ray is analyzed and discussed. We study the differential cross se…
