Abstract
We consider generic MQCD configurations with matter described by semi- infinite D4-branes and softly broken supersymmetry. We show that the m atter sector does not introduce supersymmetry breaking parameters so t hat the most relevant supersymmetry breaking operator at low energies is the gaugino mass term. By studying the run-away properties of these models in the decoupling limit of the adjoint matter, we argue that t hese softly broken MQCD configurations fair to capture the infrared ph ysics of QCD at scales below the gaugino mass.
