Event Details


Abstract: Models of new physics (NP) in which the Higgs mass-squared parameter is calculable and natural predict new states with masses not too far above the electroweak scale. While we tend to think of the location of the NP scale as determined largely by naturalness, UV considerations can lead us to expect certain states at a different scale than that necessarily required for a maximally natural theory. I will discuss two examples of this—Higgsinos in natural supersymmetry and fermionic top partners in composite Higgs models—and reasons why the masses of these states might not be what one would naïvely expect.
