  Split higgsinos are a compelling class of models to explain dark matter and
may be on the verge of detection by multiple current experimental avenues. The
idea is based on a large split in scales between the electroweak scale and
decoupled scalars, with relatively light higgsinos between the two. Such models
enjoy the merit of depending on very few parameters while still explaining
gauge coupling unification, dark matter, and most of the hierarchy between the
Planck and electroweak scales, and they remain undetected by past experiments.
We analyze split higgsinos in view of current and next generation experiments.
We discuss the direct and indirect detection prospects and further demonstrate
promising discovery potentials in the upcoming electron electric dipole moment
experiments. The parameter space of this model is analyzed in terms of
experiments expected to run in the coming years and where we should be looking
for the next potential discoveries.
