Gauge/String Duality in Confining Theories

Jose D. Edelstein, Ruben Portugues

This is the content of a set of lectures given at the XIII Jorge Andre Swieca Summer School on Particles and Fields, held in Campos do Jordao, Brazil in January 2005. They intend t…

Deforming baryons into confining strings

Sean A. Hartnoll, Ruben Portugues

We find explicit probe D3-brane solutions in the infrared of the Maldacena-Nunez background. The solutions describe deformed baryon vertices: q external quarks are separated in spa…

Membrane solitons in eight-dimensional hyper-Kaehler backgrounds

Ruben Portugues

We derive the BPS equations satisfied by lump solitons in -dimensional sigma models with toric 8-dimensional hyper-Kähler () target spaces and check they preserve 1/…

The chiral anomaly from M theory

Umut Gursoy, Sean A. Hartnoll, Ruben Portugues

We argue that the chiral anomaly of $\Ncal = 1$ super Yang-Mills theory admits a dual description as spontaneous symmetry breaking in M theory on holonomy manifolds. We ident…

Missing Yang-Mills instantons on ALE spaces

Sean A. Hartnoll, Ruben Portugues

Paper withdrawn due to a crucial algebraic error in section 3.

Intersoliton forces in the Wess-Zumino model

Ruben Portugues, Paul K. Townsend

The spectrum of supersymmetric domain wall solitons of the Wess-Zumino model is known to be discontinuous across a curve (of marginal stability) in the moduli space of quartic supe…

D-brane Solitons in Supersymmetric Sigma-Models

Jerome P. Gauntlett, Rubén Portugues, David Tong +1

Massive D=4 N=2 supersymmetric sigma models typically admit domain wall (Q-kink) solutions and string (Q-lump) solutions, both preserving 1/2 supersymmetry. We exhibit a new static…
