Webs of 3d 𝒩 = 2 dualities with D-type superpotentials

Abstract

Abstract We study 3d 𝒩 = 2 dualities arising from the compactification of 4d 𝒩 = 1 Usp(2n) SQCD with two antisymmetric rank-two tensors and Dk+2-type superpotential, with odd k. The analysis is carried out by using field theory methods and by checking the various steps on the three sphere partition function. Most of the results are based on a conjectural confining duality that we do not prove but that fits consistently with the web of dualities that we obtain. Along the analysis we recover dualities already claimed in the literature and we propose new ones. The final picture that emerges fits with the general scheme worked out for ordinary SQCD and for adjoint SQCD with Ak-type superpotentials.
