Simple models with both baryon and lepton number violation by two units
Andreas Helset, Clara Murgui, Mark B. Wise
We construct simple renormalizable extensions of the standard model where the leading baryon number violating processes have . These models contain additional sca…
EWPD in the SMEFT to dimension eight
Tyler Corbett, Andreas Helset, Adam Martin +1
We calculate the corrections to LEP electroweak precision data using the geometric formulation of the Standard Model Effec…
Exact SMEFT formulation and expansion to
Chris Hays, Andreas Helset, Adam Martin +1
The Standard Model Effective Field Theory (SMEFT) theoretical framework is increasingly used to interpret particle physics measurements and constrain physics beyond the Standard Mo…
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…
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…
