Winding String Dynamics in a Time-Dependent Beta Deformed Background
Abstract
Description
We study string theory on the analytically continued $β$ deformed background proposed in hep-th/0509036. This non-static model provides a solvable conformal field theory which describes time-dependent twisted string dynamics. With the mini-superspace approach, we examine disk one-point correlators of D-branes and compute the winding string pair production rate. We find that these results are consistent with the CFT computation.
