Title: Predicting the superpartner spectrum from partially composite supersymmetry

Abstract

We use the idea of partial compositeness in a minimal supersymmetric model to relate the fermion and sfermion masses. By assuming that the Higgs and third-generation matter is (mostly) elementary, while the first- and second-generation matter is (mostly) composite, the Yukawa coupling hierarchy can be explained by a linear mixing between elementary states and composite operators with large anomalous dimensions. If the composite sector also breaks supersymmetry, then composite sfermions such as selectrons are predicted to be much heavier than the lighter elementary stops. This inverted sfermion mass hierarchy is consistent with current experimental limits that prefer light stops (O(10) TeV) to accommodate the 125 GeV Higgs boson, while predicting heavy first- and second-generation sfermions (≳100 TeV) as indicated by flavor physics experiments. The underlying dynamics can be modeled by a dual 5D gravity theory that also predicts a gravitino dark matter candidate (≳ keV), together with gauginos and Higgsinos, ranging from 10–90 TeV, that are split from the heavier first- and second-generation sfermion spectrum. This intricate connection between the fermion and sfermion mass spectrum can be tested at future experiments.
