Название: Non-Perturbative aspects in supersymmetric gauge theories

Авторы: Amati D., Konishi K., Rossi G.C.


We review our present understanding of those non-perturbative features of supersymmetric gauge theories that are believed to determine the
properties of then ground states (vacua). A wide variety of theories is discussed in detail: pure Yang-Mills, theories with massive or massless real
matter fields, theories with chiral matter, both for SU(Af) and for the case of a general compact gauge group (as for instance H8). Depending on
some general features of the theory under consideration, various (perhaps) unexpected phenomena are shown to occur. Among these the
breakdown of the (per.urbatively established) non-renormalization theorem, the occurrence of runaway vacua in certain limits, the spontaneous
dynamical breaking of sipersymmetry itself in some chiral theories. Throughout the report we restrict ourselves to the confining picture instanton
method, occasionally complementir.g it with the information coming from chiral and supersymmetric Ward-Takahashi identities. We compare our
results with the ones suggested eHier by effective Lagrangian methods and, only briefly, with those obtained by other groups in the Higgs picture.
