  Intersecting D-brane models in string theory can naturally support the gauge
and matter content of left-right symmetric extensions of the Standard Model
with gauge symmetry SU(3)_c x SU(2)_L x SU(2)_R x U(1)_{B-L}. Considering such
models as candidates for explaining the 2TeV excesses seen in Run-1 by both
ATLAS and CMS, the minimal possible scale of supersymmetry breaking is
determined by the requirement of precise one-loop gauge coupling unification.
For the vector-like, bifundamental and (anti-)symmetric Higgs content of such
brane configurations, this comes out fairly universally at around 19TeV. For
the SU(2)_R gauge coupling one finds values 0.48<g_R(M_R)<0.6. Threshold
corrections can potentially lower the scale of supersymmetry breaking.
