Counting axions with IAXO
BenjamÃn Grinstein, Carlos Miró, Pablo QuÃlez Lasanta
The existence of multiple axion species is a generic prediction of a number of extensions of the Standard Model. If more than one axion couples to photons, their combined signal in…
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…
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…
How large could CP violation in neutral meson mixing be? Implications for baryogenesis and upcoming searches
Carlos Miró, Miguel Escudero, Miguel Nebot
CP violation in neutral meson oscillations is an experimental observable that could be directly related to the baryon asymmetry of the Universe through the -Mesogenesis mech…
