High Energy Theory Lunchtime Seminar

Friday, March 9th 2018
Speaker: Stephen Martin (Northern Illinois U.)
Subject: Quasi-fixed points from scalar sequestering in supersymmetry

The little hierarchy problem of supersymmetry has to do with the question of why the electroweak breaking scale is small compared to the increasingly stringent lower limits on superpartner masses from the LHC. I discuss the possibility of addressing this problem by using hidden sector superconformal renormalization effects. This drives the soft supersymmetry breaking scalar squared mass terms in the Minimal Supersymmetric Standard Model towards quasi-fixed points in the infrared. I discuss the features of such models, and the extent to which the quasi-fixed point effects may ameliorate the little hierarchy problem.
