Abstract

Abstract: We show that upper bounds on the masses for gluino, squarks and higgsino are mgluino ≤5.5 TeV, msquark ≤ 4.7 TeV and mhiggsino ≤ 650 GeV in a focus point gaugino mediation. Here, we impose a mild fine tuning Δ ≤ 100. This result shows that it is very challenging for the LHC to exclude the focus point gaugino mediation with the mild fine tuning. However, the ILC may have a potential for excluding the focus point gaugino mediation with such a mild fine tuning. It is also shown that vector-like matters reduce the required masses of the squark (stop) and gluino to explain the observed Higgs boson mass and enhance the testability of the model at the LHC. The fine-tuning is still kept mild.
