Abstract
Supersymmetric models with t-b-Ï Yukawa coupling unification and unified gaugino masses at the GUT scale-with μ>0-show a mild preference for light gluino masses mgËâ²500GeV. This range of mgË is now essentially ruled out by LHC searches. We show that a heavier gluino with mgËâ¼0.5-3TeV can also be compatible with excellent t-b-Ï Yukawa coupling unification in supersymmetric models with non-universal Higgs masses (NUHM2). The gluino in such models is the lightest colored sparticle, while the squark sector displays an inverted mass hierarchy with mqËâ¼5-20TeV. We present some LHC testable benchmark points for which the lightest Higgs boson mass mhâ125GeV. We also discuss LHC signatures of Yukawa-unified models with heavier gluinos. We expect gluino pair production followed by decay to final states containing four b-jets plus four W-bosons plus missing ET to occur at possibly observable rates at LHC.
