Conservative Dynamics of Binary Systems at Fourth Post-Minkowskian Order in the Large-eccentricity Expansion
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We compute the conservative dynamics of non-spinning binaries at fourth Post-Minkowskian order in the large-eccentricity limit, including both potential and radiation-reaction tail…
The old conformal bootstrap revisited
Pedro Liendo, Zhengwen Liu, Junchen Rong
The "old" conformal bootstrap was originally formulated by Migdal and Polyakov (MP) as a method for calculating conformal dimensions self-consistently. In this work we revisit the…
Infrared photons and asymptotic symmetries
Zhengwen Liu, Pujian Mao
S-matrix elements exhibit universal factorization when multiple infrared photons are emitted in scattering processes. We explicitly show that the leading soft factorization of tree…
Dynamics of Binary Systems to Fourth Post-Minkowskian Order from the Effective Field Theory Approach
Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1
We present the contribution from potential interactions to the dynamics of non-spinning binaries to fourth Post-Minkowskian (4PM) order. This is achieved by computing the scatterin…
Spin Effects in the Effective Field Theory Approach to Post-Minkowskian Conservative Dynamics
Zhengwen Liu, Rafael A. Porto, Zixin Yang
Building upon the worldline effective field theory (EFT) formalism for spinning bodies developed for the Post-Newtonian regime, we generalize the EFT approach to Post-Minkowskian (…
