Query: Chiral gauge dynamics and dynamical supersymmetry breaking   We study the dynamics of a chiral SU(2) gauge theory with a Weyl fermion in
the I=3/2 representation and of its supersymmetric generalization. In the
former, we find a new and exotic mechanism of confinement, induced by
topological excitations that we refer to as magnetic quintets. The
supersymmetric version was examined earlier in the context of dynamical
supersymmetry breaking by Intriligator, Seiberg, and Shenker, who showed that
if this gauge theory confines at the origin of moduli space, one may break
supersymmetry by adding a tree level superpotential. We examine the dynamics by
deforming the theory on S^1 x R^3, and show that the infrared behavior of this
theory is an interacting CFT at small S^1. We argue that this continues to hold
at large S^1, and if so, that supersymmetry must remain unbroken. Our methods
also provide the microscopic origin of various superpotentials in SQCD on S^1 x
R^3 - which were previously obtained by using symmetry and holomorphy - and
resolve a long standing interpretational puzzle concerning a flux operator
discovered by Affleck, Harvey, and Witten. It is generated by a topological
excitation, a "magnetic bion", whose stability is due to fermion pair exchange
between its constituents. We also briefly comment on composite monopole
operators as leading effects in two dimensional anti-ferromagnets.
