Heavy quarks and tau leptons: New physics opportunities
Alejandro Celis
In this talk I discuss the role of heavy quarks in new physics searches with tau leptons. I focus on new physics effects associated to the scalar sector which are naturally enhance…
decays in the aligned two-Higgs-doublet model
Alejandro Celis
In this talk I review the status of decays within the framework of the aligned two-Higgs-doublet model.
A class of invisible axion models with FCNCs at tree level
Alejandro Celis, Javier Fuentes-Martin, Hugo Serodio
We build a class of invisible axion models with tree-level Flavor Changing Neutral Currents completely controlled by the fermion mixing matrices. The scalar sector of these models…
An invisible axion model with controlled FCNCs at tree level
Alejandro Celis, Javier Fuentes-Martin, Hugo Serodio
We derive the necessary conditions to build a class of invisible axion models with Flavor Changing Neutral Currents at tree-level controlled by the fermion mixing matrices and pres…
Disentangling new physics contributions in lepton flavour violating tau decays
Alejandro Celis, Vincenzo Cirigliano, Emilie Passemar
The possibility to discriminate between different operators contributing to lepton flavour violating tau decays is discussed within an effective field theory framework. Correlation…
Effective Aligned 2HDM with a DFSZ-like invisible axion
Alejandro Celis, Javier Fuentes-Martin, Hugo Serodio
We discuss the possibility of having a non-minimal scalar sector at the weak scale within the framework of invisible axion models. To frame our discussion we consider an extension…
