| Finite endpoint momentum strings and applications to energy loss |
| Speaker: | Andrej Ficnar (Columbia University) |
| Abstract: | I will argue that classical strings, both bosonic and supersymmetric, can have finite energy and momentum at their endpoints. I will also show that, in a general curved background, the string endpoints must propagate along null geodesics as long as their energy remains finite. Finite endpoint momentum allows strings with a fixed energy to travel a greater distance in an AdS5-Schwarzschild background than has been possible for classical solutions considered previously. I will also review the relevance to heavy ion phenomenology of the dependence of this distance on energy and propose a scheme for determining the instantaneous rate of energy loss. |
