A major goal of axion searches is reaching inside the parameter space region of realistic axion models. Currently, the boundaries of this region depend on somewhat arbitrary criteria, and it would be desirable to specify them in terms of precise phenomenological requirements. In this talk I put forth a definition for a phenomenologically preferred axion window as the region encompassing all...
The absence of anti-matter in our universe hints towards new sources of CP violation that are not present in the Standard Model. One possible source of such CP violation could hide in the interactions of the Higgs boson. I will discuss the framework of the Standard Model effective field theory in which such anomalous CP-violating Higgs interactions appear naturally. Footprints of Higgs CP...
I will analyze the general structure of mirror symmetry breaking in the Twin Higgs scenario. A significant gain in fine tuning can be achieved if the symmetry is broken hardly. I will emphasize that weakly coupled UV completions can naturally accommodate this scenario. I will analyze SUSY UV completions and present a simple Twin SUSY model with a tuning of around 10% and colored superpartners...
I will present DsixTools, a Mathematica package for the handling of
the dimension six Standard Model Effective Field Theory. Among other
features, DsixTools allows the user to perform the full 1-loop
Renormalization Group Equations (RGEs) evolution of the Wilson
coefficients in the Warsaw basis. This is achieved thanks to the
SMEFTrunner module, which implements the full 1-loop RGEs...
I will discuss the impact of the measured Higgs mass and of LHC searches on the parameter space of gaugino-mediated supersymmetry breaking. Including non-vanishing trilinear scalar couplings, which were originally thought not to be present in this model, allows to obtain the correct Higgs mass for superparticle masses that are accessible by the LHC. I will also comment on the effects of more...
We will review the main features of the 3-3-1 models. These sort of models are interesting proposals for the physics beyond the standard model because they are free of anomalies only if the number of families or generations is three. Usually, the models are classified according a parameter (denoted by β) appearing in the electric charge operator.
In particular, we show that the β parameter is...
We will present the theory that explains the hierarchy of charged fermion masses through a clockwork mechanism and discuss its phenomenological implications.
The approximate SM flavor symmetries could have emerged from dynamical scenarios in which the corresponding SM fermions couple to a strong sector, responsible for electroweak symmetry breaking, at different dynamical scales. Surprisingly, these scenarios are able to pass all flavor and CP-violating constraints.
