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…

The Geometric Universal One-Loop Effective Action
Xu-Xiang Li, Xiaochuan Lu, Zhengkang Zhang
We derive universal formulae for integrating out heavy degrees of freedom in scalar field theories up to one-loop level in terms of covariant quantities associated with the geometr…
