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…
Heavy Black Hole Effective Theory
Poul H. Damgaard, Kays Haddad, Andreas Helset
We formulate an effective field theory describing large mass scalars and fermions minimally coupled to gravity. The operators of this effective field theory are organized in powers…
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…
