title = "Gauge hierarchy in SU(3)c×SU(3)L×SU(3)R and low energy implications",
abstract = "We explore the gauge hierarchy problem within the framework of supersymmetric SU(3)c×SU(3)L×SU(3)R with a minimal set of Higgs supermultiplets. Imposition of a suitable discrete (alternatively R) symmetry {"}prevents{"} the electroweak Higgs doublets from becoming superheavy through renormalizable couplings. A full resolution of the problem requires consideration of the non-renormalizable couplings which play an essential role. Other key differences from the minimal supersymmetric SU(5) model include the fact that the proton is stable and that an effective 5+5 supermultiplet appears around the TeV mass scale.",

note = "Funding Information: The presently measured gauge couplings of the standard model, when extrapolated to higher energies with supersymmetry (SUSY) becoming relevant at scales ~ 100 GeV - few TeV, appear to merge together at scales around 1016 GeV \[1 \]. This certainly is a boost for ideas based on supersymmetric grand unification \[2\]w, ith SUSY SU(5) or SO(10) being the obvious candidates. However, a potential drawback for SU(5) type models is that they cannot be {"}embedded{"} in any {"}straightforward{"} superstring approach, which has led to renewed interest in gauge groups such as G = SU(3)c X SU(3)L × SU(3)R. The gauge group G not only emerges from the simplest superstring theories ¢' Supportedi n part by Department of Energy Grant No. DE-FG02-91ER40626.
