heal.abstract	We examine the static potential in the presence of flavors in the perturbative backreacted D4/D8 system from localized D8 branes, focusing, in particular, on the Sakai- Sugimoto model. For the case of long strings we find the flavor corrections to the static potential which are of exponential form. We then investigate shorter Wilson loops and express their energy analytically in terms of the lengths of two neighboring Wilson loops. Moreover, we find that beyond a certain scale the static force in the backreacted background is reduced compared to one in the probe limit, as expected due to screening effects. We also compare the string world sheets in the two backgrounds and find how they get modified by the backreaction. Our results are supported by numerical computations as well. Finally, we discuss our results in comparison with the lattice data. © 2012 American Physical Society.	en
