Descripción
In the high-scale (split) MSSM, the measured Higgs mass sets an upper bound on the supersymmetric scalar mass scale $M_S$ around 10^10 (10^8) GeV, for tan beta in the standard range and the central value of the top mass. This work demonstrates that $M_S$ can be pushed up close to the Planck scale while reproducing a correct Higgs mass due to potentially large negative sbottom/stau threshold corrections to the Higgs quartic coupling. This mechanism applies to the split as well as the high-scale MSSM. Also discussed is the constraint from the vacuum stability.
