Strings between branes
D-brane configurations containing fundamental strings are constructed as classical solutions of Yang-Mills theory. The fundamental strings in these systems stretch between D-branes. In the case of D1-branes, this construction gives smooth (classical) resolutions of string junctions and string networks. Using a non-abelian Yang-Mills analysis of the string current, the string charge density is c...
متن کاملBorn-Infeld strings between D-branes
We examine the solutions of world-volume action for a D3-brane being put near other D3-brane which is replaced by the background configuration of bulk space. It is shown that the BPS solutions are not affected by the D3brane background, and they are interpreted as dyonic strings connecting two branes. On the contrary, the non-BPS configurations are largely influenced by the background D-brane, ...

متن کاملHorizon Branes and Chiral Strings
String Theory is known to be one possible model to unify all the known forces of the Nature by a universal concept, that of strings. All fundamental particles, including gravitons with a given energy, are supposed to be oscillating states of tensive open or closed strings. The string concept introduces some non-locality in the gravitational interactions, making the self-interacting Feynman diag...
متن کاملOpen Strings on AdS2 Branes
We study the spectrum of open strings on AdS2 branes in AdS3 in an NS-NS background, using the SL(2, R) WZW model. When the brane carries no fundamental string charge, the open string spectrum is the holomorphic square root of the spectrum of closed strings in AdS3. It contains short and long strings, and is invariant under spectral flow. When the brane carries fundamental string charge, the op...
