\end{array} \nonumber$$ Analyzing the ’t Hooft anomaly matching conditions one concludes that some of the global symmetries of the theory have to be broken, which is the effect of a classical constraint on the composite fields being modified by quantum dynamics. It was shown in [@Seiberg] that the form of the quantum modified constraint is given by[^4] $${\rm det} \mathcal{M}_i -  \mathcal{B}_i \tilde{\mathcal{B}}_i = \Lambda^{2M}_2.$$ Thus there is a branch on the moduli space where the global $SU(M)_{2i-1}\times SU(M)_{2i+1}$ is broken to a diagonal $SU(M)$, which is when ${\rm det} \mathcal{M}_i$ has an expectation value. Turning on the baryons $\mathcal{B}_i$ and $\tilde{\mathcal{B}}_i$ does not break the global symmetry group. Hence, in order to lift the branch of moduli space with ${\rm det} \mathcal{M}_i=0$ (and also to get rid of unwanted massless singlets) one is forced to introduce two singlets $L_i$ and $\tilde{L}_i$ and add a tree level superpotential, $$\label{eq:supB}
W_{\rm tree} =
\frac{1}{\mu^{M-2}}(L_i \mathcal{B}_i + \tilde{L}_i \tilde{\mathcal{B}}_i),$$ where the scale $\mu$ would have to be regarded as a cutoff scale of the theory (perhaps originating from some other strong dynamics). The $Q_i$’s in (\[fieldcontent\]) should then be identified with the composite meson field $\mathcal{M}_i$, and the baryons
