Chern-Simons and RG Flows: Contact with Dualities

Understand

Contact terms in two point functions of global symmetry currents have recently been proposed as a check of Seiberg-like duality in three dimensional supersymmetric field theories.

• In this paper we compute the contact terms for various N=2 dual pairs in flat space.
• We show that the results of this computation agree with the ones obtained from localization.
• We study dual pairs of gauge theories with (anti-)fundamental matter fields, and some special examples of dual pairs with adjoint and antisymmetric matter fields.
