Matching of the perturbative mass spectra
-----------------------------------------

Now that we understand how the model in (\[fieldcontent\]) could arise from supersymmetric gauge dynamics, we analyze the various mass spectra of the model assuming that the symmetry breaking vev’s have been generated. The aim of this analysis is to show that one indeed recovers a higher dimensional supersymmetric theory in the limit of $N\to \infty$, and that the number of supercharges is appropriately doubled. In order to be able to analyze the massive spectrum of the model (and not just the extreme infrared like in [@CEFS]) we assume that the scale $v$ is larger than the dynamical scale of the $SU(M)$ gauge group $\Lambda < v$. This would indeed follow in the dynamically generated examples considered above, because there $v=\Lambda_2\gg \mu \gg \Lambda_1$. In this case the gauge groups are broken before they could become strongly interacting, and a conventional perturbative analysis is possible. Then the singlet field corresponding to $B_i$ can be identified at the lowest order in the fluctuations with $v^{N-1} {\rm tr} Q_i$, and therefore the mass term for the fields $S_i$ and ${\rm tr} Q_i$ from (\[suppot\]) is given by $v (\frac{v}{\mu})^{M-2} \gg
