Abstract
A recent signal of 750 GeV diphotons at the LHC can be explained within the framework of supersymmetric unification by the introduction of vector quarks and leptons with Yukawa couplings to a singlet S that describes the 750 GeV resonance We study the most general set of theories that allow successful gauge coupling unification and find that these Yukawa couplings are severely constrained by renormalization group behavior they are independent of ultraviolet physics and flow to values at the TeV scale that we calculate precisely As a consequence the vector quarks and leptons must be light typically in the region of 375 GeV to 700 GeV and in certain cases up to 1 TeV The 750 GeV resonance may have a width less than the experimental resolution alternatively with the mass splitting between scalar and pseudoscalar components of S arising from oneloop diagrams involving vector fermions we compute an apparent width of 10s of GeVThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
