Most general EFTs from spurion analysis: Hilbert series and Minimal Lepton Flavor Violation
Benjamín 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
Benjamín 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…

Light states in real multi-Higgs models with spontaneous CP violation
Carlos Miró, Miguel Nebot, Daniel Queiroz
In models with extended scalar sectors consisting of multiple Higgs doublets that trigger spontaneous electroweak symmetry breaking, it might be expected that the abundance of dime…
