On Renormalization Group Flows and Exactly Marginal Operators in Three Dimensions
Matthew J. Strassler
As in two and four dimensions, supersymmetric conformal field theories in three dimensions can have exactly marginal operators. These are illustrated in a number of examples with N…
QCD, Supersymmetric QCD, Lattice QCD and String Theory: Synthesis on the Horizon?
Matthew J. Strassler
Supersymmetric gauge theories in four dimensions have taught us many important physics lessons. These can both inform and be informed by future work on the lattice. I focus on thre…
On Phases of Gauge Theories and the Role of Non-BPS Solitons in Field Theory
Matthew J. Strassler
As shown in hep-th/9709081, non-BPS saturated solitons play an important role in the duality transformations of N=1 supersymmetric gauge theories. In particular, a massive spinor i…
A One-Scale Model of Dynamical Supersymmetry Breaking
Ann Nelson, Matthew J. Strassler
A model of gauge-mediated supersymmetry breaking is constructed in which the low-energy physics depends on a single dynamical scale. Strong coupling dynamics of gauge theories play…
Finite Theories and Marginal Operators on the Brane
Amihay Hanany, Matthew J. Strassler, Angel M. Uranga
We show how to use D and NS fivebranes in Type IIB superstring theory to construct large classes of finite N=1 supersymmetric four dimensional field theories. In this construction,…
Messages for QCD from the Superworld
Matthew J. Strassler
Recent discoveries in supersymmetric gauge theories have significant implications for our understanding for QCD and of field theory in general. The phases of N=1 supersymmetric QCD…
