A softly broken susy SU(5) gut with no light supersymmetric partners, and massive superspace

Research output: Contribution to journal › Article › peer-review

Abstract

A softly broken supersymmetric grand unified theory based on SU(5) with no light superpartners is constructed. The model does not involve fine tuning and gives to a stable hierarchy. The choice of mass parameters is dictated by the massive superspace (MASSP). All superpartners of ordinary particles have masses {greater-than or approximate} 10¹¹ GeV. The proton decay proceeds via dimension-5 operators and is mediated by squarks, sleptons, shiggses and gauginos leading to a lifetime >10³² yr. The cosmological constant is zero.
