摘要
We show that upper bounds on the masses for gluino, squarks and higgsino are m (gluino) a parts per thousand currency sign5.5 TeV, m (squark) a parts per thousand currency sign 4.7 TeV and m (higgsino) a parts per thousand currency sign 650 GeV in a focus point gaugino mediation. Here, we impose a mild fine tuning Delta a parts per thousand currency sign 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.
