Description
The most basic requirement for naturalness in supersymmetric models is the
existence of rather light partners of the Higgs boson, the Higgsinos, at
masses not too far above M_Z. Despite the pressure from LHC data on the simplest
high-scale models (like the cMSSM), such light Higgsinos can still be
realised in different types of GUT-scale models from NUHM2 to mirage
unification models. The ILC will offer the unique discovery potential

for the elusive higgsino particles and allow for precision measurements
of their properties. In this contribution, prospects for the achievable
precisions for masses, the very small mass splittings and polarised production
cross sections will be presented. Based on these, we studied the possibilities to
determine the SUSY parameters at the weak scale, and to extrapolate their
running to the GUT scale. We will discuss the prospects to thereby
differentiate between various GUT-scale models and SUSY breaking schemes and
to predict the masses of the remaining SUSY particles. In particular the
latter could provide important guidance for the energy scale of the
next hadron collider after the LHC.
