• Gauge coupling unification is one of main motivations in the split-SUSY scenario, in which the existence of grand unified theories (GUTs) is assumed. We examine how to realize a split-SUSY mass spectrum in the context of GUTs and find that the construction of split-SUSY GUTs is by no means straightforward. With R-symmetry breaking sources in the GUT sector, GUT particles play the role of messengers in the gauge mediation scenario, and their contributions to gaugino masses can be large. We find an upper bound on soft scalar masses of 〓(10^<10>) GeV from the condition of consistency in constructing the split-SUSY GUT. Also, we discuss an attempt to construct R-symmetric GUT models.
