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…
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…
Anomalies From the Covariant Derivative Expansion
Timothy Cohen, Xiaochuan Lu, Zhengkang Zhang
We revisit the calculation of anomalies for global and gauge symmetries in the framework of the Covariant Derivative Expansion (CDE). Due to the presence of UV divergences, the res…
LHC EFT WG Note: Precision matching of microscopic physics to the Standard Model Effective Field Theory (SMEFT)
Sally Dawson, Admir Greljo, Kristin Lohwasser +16
This note gives an overview of the tools for the precision matching of ultraviolet theories to the Standard Model effective field theory (SMEFT) at the tree level and one loop. Sev…
Hilbert Series, the Higgs Mechanism, and HEFT
Lukáš Gráf, Brian Henning, Xiaochuan Lu +2
We expand Hilbert series technologies in effective field theory for the inclusion of massive particles, enabling, among other things, the enumeration of operator bases for non-line…
