High Energy Theory Lunchtime Seminar

Friday, November 2nd 2018
Speaker: Anson Hook (U. Maryland)
Subject: New approaches to the Hierarchy problem

We present two new approaches to the Hierarchy problem. The first utilizes non-linearly realized discrete symmetries. The cancelations occur due to a discrete symmetry that is realized as a shift symmetry on the scalar and as an exchange symmetry on the particles with which the scalar interacts. The second approach allows for a large Higgs mass, but the Higgs mass expanded around the minimum of the potential is small. This approach is analogous to models of the dilaton where the quartic is large at tree level, but small when expanded around the minimum of the potential.
