STrEAMlining EFT Matching
Timothy Cohen, Xiaochuan Lu, Zhengkang Zhang
This paper presents STrEAM (SuperTrace Evaluation Automated for Matching), a Mathematica package that calculates all functional supertraces which arise when matching a generic UV m…
Functional Prescription for EFT Matching
Timothy Cohen, Xiaochuan Lu, Zhengkang Zhang
We simplify the one-loop functional matching formalism to develop a streamlined prescription. The functional approach is conceptually appealing: all calculations are performed with…
Custodial Symmetry (Violation) in SMEFT
Graham D. Kribs, Xiaochuan Lu, Adam Martin +1
We investigate precision observables sensitive to custodial symmetric/violating UV physics beyond the Standard Model. We use the SMEFT framework which in general includes non-obliq…
2, 12, 117, 1959, 45171, 1170086, ...: A Hilbert series for the QCD chiral Lagrangian
Lukas Graf, Brian Henning, Xiaochuan Lu +2
We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extend…
Is SMEFT Enough?
Timothy Cohen, Nathaniel Craig, Xiaochuan Lu +1
There are two canonical approaches to treating the Standard Model as an Effective Field Theory (EFT): Standard Model EFT (SMEFT), expressed in the electroweak symmetric phase utili…
