# Note on D-brane effective action in the linear dilaton background

@article{Kluso2003NoteOD, title={Note on D-brane effective action in the linear dilaton background}, author={Josef Klusoň}, journal={Journal of High Energy Physics}, year={2003}, volume={2003}, pages={068-068} }

In this short note we will study effective action for unstable D-brane in the linear dilaton background. We will solve the equation of motion for large T and we will calculate the stress energy tensor. Then we compare our results with the calculations performed using exact conformal field theory description of the open string worldsheet theory.
