External Fields and Chiral Symmetry Breaking in the Sakai – Sugimoto Model

Using the Sakai–Sugimoto model we study the effect of an external magnetic field on the dynamics of fundamental flavours in both the confined and deconfined phases of a large Nc gauge theory. We find that an external magnetic field promotes chiral symmetry breaking, consistent with the “magnetic catalysis” observed in the field theory literature, and seen… CONTINUE READING
