Exact superpotentials in four dimensions.

Supersymmetric gauge theories in four dimensions can display interesting non-perturbative phenomena. Although the superpotential dynamically generated by these phenomena can be highly nontrivial, it can often be exactly determined. We discuss some general techniques for analyzing the Wilsonian superpotential and demonstrate them with simple but non-trivial examples.

Exact Hypermultiplet Dynamics in Four Dimensions

The hypermultiplet low-energy effective action (LEEA) in N=2 supersymmetric four-dimensional (4d) gauge theories can receive both perturbative (at one loop) and non-perturbative (due to instantons) quantum corrections. The manifestly N=2 supersymmetric Feynman rules in harmonic (twistor) superspace are used to calculate the perturbative hypermultiplet LEEA that results in the Taub-NUT non-linea...

Exact primordial black strings in four dimensions.

A solution of effective string theory in four dimensions is presented which admits interpretation of a rotating black cosmic string. It is constructed by tensoring the three dimensional black hole, extended with the Kalb-Ramond axion, with a flat direction. The physical interpretation of the solution is discussed, with special attention on the axion, which is found to play a role very similar t...

On exact superpotentials in confining vacua

We consider the N = 1 super Yang-Mills theory with gauge group U(N) or SU(N) and one adjoint Higgs field with an arbitrary polynomial superpotential. We provide a purely field theoretic derivation of the exact effective superpotential W (S) for the glueball superfield S = −W W a α/(32Nπ) in the confining vacua. We show that the result matches with the Dijkgraaf-Vafa matrix model proposal. The p...

Exact low-energy effective actions for hypermultiplets in four dimensions

We consider the general hypermultiplet low-energy effective actions (LEEA) that may appear in four-dimensional, N=2 supersymmetric Yang-Mills theories, e.g. in the Coulomb and Higgs branches. Our main purpose is a description of the exact LEEA of n magnetically charged hypermultiplets. The hypermultiplet LEEA is given by the N=2 supersymmetric non-linear sigma-model (NLSM) with a 4n-dimensional...
