Constraining supersymmetry with heavy scalars: Using the CMB
Constraining supersymmetry with heavy scalars: Using the CMB
If low-energy supersymmetry (SUSY) exists, LHC data favors a high mass scale for scalar superpartners (above a TeV), while sfermions and the dark matter can be parametrically lighter---leading to a so-called split spectrum. When combining this fact with the motivation from fundamental theory for shift-symmetric scalars (moduli) prior to SUSY …
