  Light-front holographic quantum chromodynamics (LFHQCD) has been proposed as
an approximation to QCD which is non-perturbative and at the same time
analytically tractable. It can be derived from the holographic light-cone
Hamiltonian and effectively corresponds to a one-dimensional superconformal
quantum theory. It is proposed in this paper to extend the underlying quantum
group to N = 2 SCFT. This provides an avenue for bottom-up string theory
model-building which is firmly grounded in phenomenology. Moreover, the
peculiar properties of the model carry over to provide novel solutions to
string theory problems, including supersymmetry without predicting
superpartners as well as the breaking of the conformal symmetry and the
introduction of a low-energy scale such that the massive Virasoro modes
correspond to hadronic states reminiscent of what was once envisioned in the
Veneziano model.
