Nonlocal-in-time tail effects in gravitational scattering to fifth Post-Minkowskian and tenth self-force orders
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
Using the worldline effective field theory formalism, we derive the nonlocal-in-time conservative contributions arising from tail effects in gravitational scattering to fifth Post-…
Two-loop SYM Amplitudes via SUSY Decomposition and Massive Spinor-Helicity
Henrik Johansson, Gregor Kälin, Gustav Mogull +1
We obtain a color-kinematics-dual representation of the two-loop four-vector amplitude a general renormalizable massless SYM theory, including internal matter as ch…
Conservative Tidal Effects in Compact Binary Systems to Next-to-Leading Post-Minkowskian Order
Gregor Kälin, Zhengwen Liu, Rafael A. Porto
Using the Effective Field Theory approach together with the Boundary-to-Bound map, we compute the next-to-leading order (NLO) Post-Minkowskian (PM) tidal effects in the conservativ…
Conservative Dynamics of Binary Systems to Third Post-Minkowskian Order from the Effective Field Theory Approach
Gregor Kälin, Zhengwen Liu, Rafael A. Porto
We derive the conservative dynamics of non-spinning binaries to third Post-Minkowskian order, using the Effective Field Theory (EFT) approach introduced in [2006.01184] together wi…
Post-Minkowskian Effective Field Theory for Conservative Binary Dynamics
Gregor Kälin, Rafael A. Porto
We develop an Effective Field Theory (EFT) formalism to solve for the conservative dynamics of binary systems in gravity via Post-Minkowskian (PM) scattering data. Our framework co…
From Boundary Data to Bound States II: Scattering Angle to Dynamical Invariants (with Twist)
Gregor Kälin, Rafael A. Porto
We recently introduced in [1910.03008] a "boundary-to-bound" dictionary between gravitational scattering data and observables for bound states of non-spinning bodies. In this paper…
