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-…

Tree-level soft emission for two pairs of quarks
Xinguang Chen, Zhengwen Liu
We compute the tree-level current for the emission of two soft quark-antiquark pairs in a hard scattering. We also compute the square of this current and discuss the resulting colo…
