Flavor Corrections in the Static Potential in Holographic QCD

Understand

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 the static force for all the cases in the backreacted background is reduced compared to one in the probe limit, as expected due to screening effects.
