Equations of motion, symmetry currents and EFT below the electroweak scale
Andreas Helset, Michael Trott
The low-energy effective field theory is constructed by integrating out Standard Model states with masses proximate to the electroweak scale. We report the equations of motion for…
New Factorization Relations for Non-Linear Sigma Model Amplitudes
N. E. J. Bjerrum-Bohr, Humberto Gomez, Andreas Helset
We obtain novel factorization identities for non-linear sigma model amplitudes using a new integrand in the CHY double-cover prescription. We find that it is possible write very co…
Gauge fixing the Standard Model Effective Field Theory
Andreas Helset, Michael Paraskevas, Michael Trott
We gauge fix the Standard Model Effective Field Theory in a manner invariant under background field gauge transformations using a geometric description of the field connections.
Three-dimensional effective theories for the two Higgs doublet model at high temperature
Tyler Gorda, Andreas Helset, Lauri Niemi +2
Due to the infrared problem of high-temperature field theory, a robust study of the electroweak phase transition (EWPT) requires use of non-perturbative methods. We apply the metho…
