Abstract: A bstract We explicitly compute correlation functions with the insertion of a continuous symmetry defect in bosonic field theories. To recover its expected action on the charged operators, the definition of the defect must be modified to include a specific contact term. This can be regarded as a singular background gauge field for the global symmetry. It can be traced to the definition of the generating functional for current correlators, where the source is akin to a background gauge field for the symmetry. For holographic theories, it has been proposed that continuous symmetry defects are realized in terms of non-BPS D ( q – 1) branes. We argue that these can be regarded as $$ Dq/\overline{Dq} $$ Dq / Dq ¯ system and show its application to the case of the baryonic symmetry in the Klebanov-Witten theory. The $$ Dq/\overline{Dq} $$ Dq / Dq ¯ can be regarded as a particular regularization of the defect, holographically realizing the field theory discussion.
