D Branes and Phases on String Worldsheet

We generalize the worldsheet derivation of the topological open/closed string duality given in hep-th/0205297 to cases when there are different types of D branes on the open string side. We use the mirror Landau-Ginzburg description to clarify the correspondence between D branes on the open string side and C phases on the closed string side. We also discuss the duality from the point of view of...

Worldsheet Dynamics of String Junctions

We analyze scattering of string modes at string junctions of type IIB string theory. In the infrared limit, certain orthogonal linear combinations of the fields on the different strings satisfy either Dirichlet or Neumann boundary conditions. We confirm that the worldsheet theory of a general string network has eight conserved supercharges in agreement with target space BPS considerations. As a...

Vortices on the worldsheet of the QCD string

We investigate the properties of the QCD string in the Euclidean SU(N) pure gauge theory when the space-time dimensions transverse to it are periodic. From the point of view of an effective string theory, the string tension σ and the low-energy constants ck of the theory are arbitrary functions of the sizes of the transverse dimensions L⊥. Since the gauge theory is linearly confining in D = 2, ...

Kosterlitz-Thouless transition on the worldsheet of the QCD string

We investigate the properties of the QCD string in the Euclidean SU(N) pure gauge theory when the space-time dimensions transverse to it are periodic. We propose a generalisation of the Lüscher-Weisz effective string action for the flux-tube energy levels at finite L⊥. As the size of one transverse dimension is varied, we predict a Kosterlitz-Thouless transition of the worldsheet field theory a...

Noncommutative Gauge Dynamics From The String Worldsheet

We show how string theory can be used to reproduce the one-loop twopoint photon amplitude in noncommutative U(1) gauge theory. Using a simple realization of the gauge theory in bosonic string theory, we extract from a string cylinder computation in the decoupling limit the exact one loop field theory result. The result is obtained entirely from the region of moduli space where massless open str...
