Complete one-loop matching for a singlet scalar in the Standard Model EFT
/ Jiang, Minyuan ; Craig, Nathaniel ; Li, Ying-Ying ; Sutherland, Dave
We present the results of the first complete one-loop matching calculation between the real singlet scalar extension of the Standard Model and the Standard Model effective field theory (SMEFT) at dimension six. [...]

DEFT: a program for operators in EFT
/ Gripaios, Ben ; Sutherland, Dave
We describe a Python-based computer program, DEFT, for manipulating operators in effective field theories (EFTs). [...]

Indirect signs of the Peccei-Quinn mechanism
/ de Vries, Jordy ; Draper, Patrick ; Fuyuto, Kaori ; Kozaczuk, Jonathan ; et al
In the standard model, the renormalization of the QCD vacuum angle is extremely tiny, and small is technically natural. [...]

Exponential Hierarchies from Anderson Localization in Theory Space
/ Craig, Nathaniel ; Sutherland, Dave
We present a new mechanism for generating exponential hierarchies in four-dimensional field theories inspired by Anderson localization in one dimension, exploiting an analogy between the localization of electron energy eigenstates along a one-dimensional disordered wire and the localization of mass eigenstates along a local “theory space” with random mass parameters. [...]

Disassembling the clockwork mechanism
/ Craig, Nathaniel ; Garcia Garcia, Isabel ; Sutherland, Dave
The clockwork mechanism is a means of naturally generating exponential hierarchies in theories without significant hierarchies among fundamental parameters. [...]

An operator basis for the Standard Model with an added scalar singlet
/ Gripaios, Ben ; Sutherland, Dave
Motivated by the possible di-gamma resonance at 750 GeV, we present a basis of effective operators for the Standard Model plus a scalar singlet at dimensions 5, 6, and 7. [...]
