$USp(2N_c)$ SQCD${}_3$ with antisymmetric: dualities and symmetry enhancements

We study various aspects of the 4d/3d reduction of $\mathcal{N}=1$ dualities involving $USp(2N_c)$ gauge theories with $2N_f$ fundamentals and one antisymmetric. We discuss the non-trivial role played by the monopole superpotentials in the reduction and obtain new 3d dualities for models with both symplectic and unitary gauge groups. For $N_f=4$ we observe interesting webs of dualities and symmetry enhancements, recovering and extending some results already appeared in the literature.
