What is the Geometry of Effective Field Theories?
Timothy Cohen, Xiaochuan Lu, Zhengkang Zhang
We elaborate on a recently proposed geometric framework for scalar effective field theories. Starting from the action, a metric can be identified that enables the construction of g…

Recursion for Wilson-line Form Factors
Timothy Cohen, Marc Riembau
Matrix elements of Wilson-line dressed operators play a central role in the factorization of soft and collinear modes in gauge theories. When expressed using spinor helicity variab…
