Hilbert series for covariants and their applications to Minimal Flavor Violation
Benjamín Grinstein, Xiaochuan Lu, Luca Merlo +1
We elaborate how to apply the Hilbert series method to enumerating group covariants, which transform under any given representation, including but going beyond group invariants. Ma…
On Amplitudes and Field Redefinitions
Timothy Cohen, Xiaochuan Lu, Dave Sutherland
We derive an off-shell recursion relation for correlators that holds at all loop orders. This allows us to prove how generalized amplitudes transform under generic field redefiniti…
Constraints on the spectrum of field theories with non-integer symmetry from quantum evanescence
Weiguang Cao, Xiaochuan Lu, Tom Melia
We identify constraints in the energy spectra of quantum theories that have a global symmetry, where is treated as a continuous parameter. We point out that a class of e…
Effective Field Theories as Lagrange Spaces
Nathaniel Craig, Yu-Tse Lee, Xiaochuan Lu +1
We present a formulation of scalar effective field theories in terms of the geometry of Lagrange spaces. The horizontal geometry of the Lagrange space generalizes the Riemannian ge…
Effective Field Theory of the Two Higgs Doublet Model
Ian Banta, Timothy Cohen, Nathaniel Craig +2
We revisit the effective field theory of the two Higgs doublet model at tree level. The introduction of a novel basis in the UV theory allows us to derive matching coefficients in…
Anomaly Cancellation in Effective Field Theories From the Covariant Derivative Expansion
Timothy Cohen, Xiaochuan Lu, Zhengkang Zhang
We extend our recently-proposed formalism for calculating anomalies of global and gauge symmetries using the Covariant Derivative Expansion to include a general class of operators…
