A Note on a High-Energy Limit of Gravitational Perturbation Theory
Poul H. Damgaard, Ludovic Plante
The post-Minkowskian expansion of general relativity expands the metric in Newton's constant G around flat space-time, but much effort currently focuses on ways to extend its range…
Recursion Relations for Classical Gravity
Poul H. Damgaard, Kwangeon Kim, Kanghoon Lee
We derive a set of recursion relations for the perturbative evaluation of the scattering of two black holes in Einstein gravity. To illustrate, we solve the equations up to third p…
The Schwarzschild Black Hole from Perturbation Theory to all Orders
Poul H. Damgaard, Kanghoon Lee
Applying the quantum field theoretic perturbiner approach to Einstein gravity, we compute the metric of a Schwarzschild black hole order by order in perturbation theory. Using recu…
Scalar-Graviton Amplitudes
N. E. J. Bjerrum-Bohr, Andrea Cristofoli, Poul H. Damgaard +1
Using the CHY-formalism and its extension to a double cover we provide covariant expressions for tree-level amplitudes with two massive scalar legs and an arbitrary number of gravi…
Wilson chiral perturbation theory, Wilson-Dirac operator eigenvalues and clover improvement
Poul H. Damgaard, Urs M. Heller, Kim Splittorff
Chiral perturbation theory for eigenvalue distributions, and equivalently random matrix theory, has recently been extended to include lattice effects for Wilson fermions. We test t…
Morphology of High-Multiplicity Events in Heavy Ion Collisions
P. Naselsky, C. H. Christensen, P. R. Christensen +8
We discuss opportunities that may arise from subjecting high-multiplicity events in relativistic heavy ion collisions to an analysis similar to the one used in cosmology for the st…
