Yang-Mills observables: from KMOC to eikonal through EFTLeonardo DE LA CRUZ

In this talk we present the integrated result of NLO conservative Yang-MIlls observables in the KMOC formalism. On the other hand, extending a recently-introduced framework based on scattering amplitudes and effective field theory (EFT) to consider colour-charged objects, we obtain a conservative Hamiltonian describing the interactions of two charged bodies ...

Seminar by Gang Chen

HEFT kinematic algebra, heavy double copy and classical gravitational scattering In this talk, I will introduce the kinematic algebra and a new double copy in heavy effective field theory (HEFT). I will also present the application of the novel double copy to classical gravitational scattering. Recently we proposed a new ...

The case of the missing solutions: a biadjoint mysteryChris WHITE

A correspondence called the double copy relates quantities in gauge and gravity theories, as well as a novel scalar theory with two types of colour charge (“biadjoint scalar theory”). It is not yet known whether the double copy is fully non-perturbative, and previous attempts to double copy nonperturbative solutions of ...

Gravitational Regge bounds

Gravitational Regge bounds I will review the basic assumptions and spell out the arguments that lead to the bound on the Regge growth of gravitational scattering amplitudes. I will discuss the Regge bounds both at fixed transfer momentum and smeared over it. Our basic conclusion is that gravitational scattering amplitudes ...
