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Paper withdrawn due to a crucial algebraic error in section 3.
