On-shell heavy particle effective theories
Rafael Aoude, Kays Haddad, Andreas Helset
We introduce on-shell variables for Heavy Particle Effective Theories (HPETs) with the goal of extending Heavy Black Hole Effective Theory to higher spins and of facilitating its a…
Soft Theorems and the KLT-Relation
Rafael Aoude, Andreas Helset
We find new relations for the non-universal part of the Yang-Mills amplitudes by combining the KLT-relation and the soft behavior of gauge and gravity amplitudes. We also extend th…
The Rise of SMEFT On-shell Amplitudes
Rafael Aoude, Camila S. Machado
We present a map between the tree-level Standard Model Effective Theory (SMEFT) in the Warsaw basis and massive on-shell amplitudes. As a first step, we focus on the electroweak se…
Jet Substructure Measurements of Interference in Non-Interfering SMEFT Effects
Rafael Aoude, William Shepherd
The tails of diboson production at the LHC are sensitive to the interference between Standard Model and higher dimension operators parameterizing the effects of heavy new physics.…
