Recently the ATLAS and CMS collaborations presented preliminary results of standard model Higgs searches and reported excesses of events for a Higgs boson at 124-126 GeV. Such a Higgs mass can be naturally realized, simultaneously explaining the muon g-2 anomaly, in gauge-mediated SUSY-breaking models with extra vectorlike matters. Upper bounds are obtained on the gluino mass, m g′≲1.2(1.8)TeV, and on the extra vectorlike quark mass, MQ ≲1.0(1.8)TeV, in the parameter region where the Higgs boson mass is 124-126 GeV and the muon g-2 is consistent with the experimental value at the 1σ (2σ) level. The LHC prospects are explored in the parameter region. It is found that some of the regions are already excluded by the LHC, and most of the parameter space is expected to be covered at √s=14TeV. A study on the extra vectorlike quarks, especially current bounds on their masses and prospects for future searches, is also included.
