Description
The direct pair-production of the tau-lepton superpartner, stau, is one
of the most interesting channels to search for SUSY. First of all the stau is
with high probability the lightest of the scalar leptons. Secondly the
signature of stau pair production signal events is one of the most difficult
ones, yielding to the 'worst' and so most global scenario for the searches.
The current model-independent stau limits comes from analysis performed at
LEP but they suffer from the low energy of this facility. Limits at LHC are
extended to higher energies but they are only valid under strong constraints.
ILC, a future electron-positron collider with
energy up to 500 GeV and upgrade capability, is a promising scenario for SUSY
searches. The capability of the ILC for determining exclusion/discovery limits
for the stau in a model-independent way is shown in this contribution, together
with an overview of the current state-of-the-art.
Results of the last studies of stau pair-production at the ILC are presented,
showing the improvements with respect to previous results.
