Title: A naturally light Higgs without light Top Partners
Host: Ennio Salvioni
Room: 432
Abstract: In this talk, I will show that the inclusion of a realistic lepton sector can relax significantly the upper bound on top partner masses in minimal composite Higgs models, induced by the lightness of the Higgs boson. I will comment on the impact of different possibilities for realizing the fermion sectors on the Higgs potential, with a special emphasis on the role of the leptons, showing in particular that very minimal setups can avoid the presence of light partners in an economical and natural way.

Title: Dirac NMSSM and semi-soft SUSY breaking
Host: Ennio Salvioni
Room: 432
Abstract: The Higgs mass implies fine-tuning for minimal theories of weak-scale supersymmetry (SUSY).
Non-decoupling effects can boost the Higgs mass when new states interact with the Higgs, but new
sources of SUSY breaking that accompany such extensions threaten naturalness. We show that two
singlets with a Dirac mass can increase the Higgs mass while maintaining naturalness in the presence
of large SUSY breaking in the singlet sector. We explore the modi fied Higgs phenomenology of this
scenario, which we call the "Dirac NMSSM."
