We investigate the confining phase vacuum structure of supersymmetric
SO(11) gauge theories with one spinor matter field and N-f less than o
r equal to 6 vectors. We describe several useful tricks and tools that
facilitate the analysis of these chiral models and many other theorie
s of similar type. The forms of the N-f=5 and N-f=6 quantum moduli spa
ces are deduced by requiring that they reproduce known results for SU(
5) SUSY QCD along the spinor Rat direction. After adding mass terms fo
r vector fields and integrating out heavy degrees of freedom, we also
determine the dynamically generated superpotentials in the N-f less th
an or equal to 14 quantum theories. We close with some remarks regardi
ng magnetic duals to the N-f greater than or equal to 7 electric SO(11
) theories. (C) 1997 Published by Elsevier Science B.V.
