Most general EFTs from spurion analysis: Hilbert series and Minimal Lepton Flavor Violation
BenjamÃn Grinstein, Xiaochuan Lu, Carlos Miró +1
We derive a saturation theorem for general Effective Field Theories (EFTs) constructed using spurion analysis. Let be a set of spurion fields introduced to organize the breakin…

Accidental Symmetries, Hilbert Series, and Friends
BenjamÃn Grinstein, Xiaochuan Lu, Carlos Miró +1
Accidental symmetries in effective field theories can be established by computing and comparing Hilbert series. This invites us to study them with the tools of invariant theory. Ap…
