62. Phenomenological status of the Aligned Two-Higgs-Doublet model

Antonio Pich (IFIC, CSIC-UV)

Plenary

An updated global fit of the parameter space of the (flavour) Aligned Two-Higgs-Doublet model will be presented, taking into account improved theoretical constraints and recent LHC data. Particular attention will be devoted to the possibility that neutral and charged scalars lighter than the 125 GeV Higgs boson might exist. Sizeable regions of the parameter space remain compatible with all...

53. Non-invertible Peccei-Quinn symmetry, natural 2HDM alignment, and the visible axion

ANTONIO DELGADO (University of Notre Dame)

Plenary

We identify m12 as a spurion of non-invertible Peccei-Quinn symmetry in the type II 2HDM with gauged quark flavor. Thus a UV theory which introduces quark color-flavor monopoles can naturally realize alignment without decoupling and can furthermore revive the Weinberg-Wilczek axion. As an example we consider the SU(9) theory of color-flavor unification, which needs no new fermions. This is the...
