Counting and building operators in theories with hidden symmetries and application to HEFT
Abstract Identifying a full basis of operators to a given order is key to the generality of Effective Field Theory (EFT) and is by now a problem of known solution in terms of the Hilbert series. The present work is concerned with hidden symmetry in general and Higgs EFT in particular and (i) connect...

| Summary: | Abstract Identifying a full basis of operators to a given order is key to the generality of Effective Field Theory (EFT) and is by now a problem of known solution in terms of the Hilbert series. The present work is concerned with hidden symmetry in general and Higgs EFT in particular and (i) connects the counting formula presented in [1] in the CCWZ formulation with the linear frame and makes this connection explicit in HEFT (ii) outlines the differences in perturbation theory in each frame (iii) presents a new counting formula with measure in the full SU(3) × SU(2) × U(1) group for HEFT and (iv) provides a Mathematica code that produces the number of operators at the user-specified order in HEFT. |
