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…

The Geometric Standard Model Effective Field Theory

Andreas Helset, Adam Martin, Michael Trott

We develop the geometric formulation of the Standard Model Effective Field Theory (SMEFT). Using this approach we derive all-orders results in the $\sqrt{2 \langle H^\dagger H \ran…

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…

Ward Identities for the Standard Model Effective Field Theory

Tyler Corbett, Andreas Helset, Michael Trott

We derive Ward identities for the Standard Model Effective Field Theory using the background field method. The resulting symmetry constraints on the Standard Model Effective Field…

Baryon Number, Lepton Number, and Operator Dimension in the SMEFT with Flavor Symmetries

Andreas Helset, Andrew Kobach

For a large set of flavor symmetries, the lowest-dimensional baryon- or lepton-number violating operators in the Standard Model effective field theory (SMEFT) with flavor symmetry…

Scattering Equations and Factorization of Amplitudes II: Effective Field Theories

Humberto Gomez, Andreas Helset

We continue the program of extending the scattering equation framework by Cachazo, He and Yuan to a double-cover prescription. We discuss how to apply the double-cover formalism to…
