Theories with gauge-mediated supersymmetry breaking provide an interesting alternative to
the scenario in which the soft terms of the low-energy fields are induced by gravity. These …

We revisit the singular IIB supergravity solution describing M-fractional 3-branes on the
conifold [hep-th/0002159]. Its 5-form flux decreases, which we explain by showing that the …

Coupling fundamental quarks to QCD in the dual string representation corresponds to
adding the open string sector. Flavors therefore should be represented by space-time filling …

A bstract Many examples of low-energy dualities have been found in supersymmetric gauge
theories with four supercharges, both in four and in three space-time dimensions. In these …

I derive a procedure to count chiral primary states in N= 1 superconformal field theories in
four dimensions. The chiral primaries are counted by putting the N= 1 field theory on S3× R. I …

An exact and general solution is presented for a previously open problem. We show that the
superconformal R-symmetry of any 4d SCFT is exactly and uniquely determined by a …

Dynamical supersymmetry breaking in a long-lived meta-stable vacuum is a
phenomenologically viable possibility. This relatively unexplored avenue leads to many new …

The results of Römelsberger for an N= 1 superconformal index counting protected operators,
satisfying a BPS condition and which cannot be combined to form long multiplets, are …

We derive general bounds on operator dimensions, central charges, and OPE coefficients in
4D conformal and\(\mathcal {N}= 1\) superconformal field theories. In any CFT containing a …
