Statistical approach to Higgs couplings in the standard model effective field theory
Christopher W. Murphy
We perform a parameter fit in the Standard Model Effective Field Theory (SMEFT) with an emphasis on using regularized linear regression to tackle the issue of the large number of p…
Standard Model EFT and Extended Scalar Sectors
Sally Dawson, Christopher W. Murphy
One of the simplest extensions of the Standard Model is the inclusion of an additional scalar multiplet, and we consider scalars in the singlet, triplet, and quartet repr…
NLO Perturbativity Bounds on Quartic Couplings in Renormalizable Theories with -like Scalar Sectors
Christopher W. Murphy
The apparent breakdown of unitarity in low order perturbation theory is often is used to place bounds on the parameters of a theory. In this work we give an algorithm for approxima…
Fuzzy Dark Matter from Infrared Confining Dynamics
Hooman Davoudiasl, Christopher W. Murphy
A very light boson of mass eV may potentially be a viable dark matter (DM) candidate which can avoid phenomenological problems associated with cold DM. Such…
