Open Wilson Lines and Chiral Condensates in Thermal Holographic QCD

Understand

We investigate various aspects of a proposal by Aharony and Kutasov arXiv:0803.3547 [hep-th] for the gravity dual of an open Wilson line in the Sakai-Sugimoto model or its non-compact version.

• In particular, we use their proposal to determine the effect of finite temperature, as well as background electric and magnetic fields, on the chiral symmetry breaking order parameter.
• We also generalize their prescription to more complicated worldsheets and identify the operators dual to such worldsheets.
