Simone Blasi: A Natural Composite Higgs via Universal Boundary Conditions

Thursday 7 May 2020, 15:00 → 16:00 Europe/Zurich

Zoom only (CERN)

Composite Higgs models are under pressure due to the non-observation
of light top partners at the LHC pushing the overall fine-tuning in concrete realizations towards the percent level. In this talk we will present a novel composite Higgs in which all resonances can be naturally above 2 TeV without increasing the tuning above the minimal 10% already implied by LEP. The essential ingredients are two recently introduced concepts of soft breaking of the Higgs shift symmetry and maximal symmetry, which turn out to perfectly complement each other. The 5D realization of this model is particularly simple:
universal UV and IR boundary conditions for the bulk fermions containing the SM fields will cure the problems of existing holographic composite Higgs models.
