Abstract
Intersecting Dbrane models in string theory can naturally support the gauge and matter content of leftright symmetric extensions of the Standard Model with gauge symmetry SU3 c × SU2 L × SU2 R × U1 B−L Considering such models as candidates for explaining the 2 TeV excesses seen in Run1 by both ATLAS and CMS the minimal possible scale of supersymmetry breaking is determined by the requirement of precise oneloop gauge coupling unification For the vectorlike bifundamental and antisymmetric Higgs content of such brane configurations this comes out fairly universally at around 19 TeV For the SU2 R gauge coupling one finds values 048 g R M R 06 Threshold corrections can potentially lower the scale of supersymmetry breakingThis 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
