More on a holographic dual of QCD
Tadakatsu Sakai, Shigeki Sugimoto
We investigate the interactions among the pion, vector mesons and external gauge fields in the holographic dual of massless QCD proposed in a previous paper, hep-th/0412141, on the…
Topological B-Model, Matrix Models, Strings and Quiver Gauge Theories
Harald Ita, Harald Nieder, Yaron Oz +1
We study topological and integrable aspects of strings. We consider the circle line theories 0A and 0B at particular radii, and the super affine theories at their self-…
D-branes in N=2 Strings
Dan Gluck, Yaron Oz, Tadakatsu Sakai
We study various aspects of D-branes in the two families of closed N=2 strings denoted by αand βin hep-th/0211147. We consider two types of N=2 boundary conditions, A-type and B-ty…
Probing Flavored Mesons of Confining Gauge Theories by Supergravity
Tadakatsu Sakai, Jacob Sonnenschein
We incorporate massive flavored fundamental quarks in the supergravity dual of N=1 SYM by introducing D7 brane probes to the Klebanov Strassler background. We find probe configurat…
The Effective Action and Geometry of Closed N=2 Strings
Dan Gluck, Yaron Oz, Tadakatsu Sakai
N=2 closed strings have been recently divided in hep-th/0211147 to two T-dual families denoted by αand β. In (2,2) signature both families have one scalar in the spectrum. The scal…
Holographic Renormalization Group
Masafumi Fukuma, So Matsuura, Tadakatsu Sakai
The holographic renormalization group (RG) is reviewed in a self-contained manner. The holographic RG is based on the idea that the radial coordinate of a space-time with asymptoti…
