A Toolkit for Ortho-Symplectic Dualities


We propose new confining dualities in 3d $$ N $$= 2 gauge theories with orthogonal gauge groups, with and without monopole superpotentials. Deriving some of those dualities requires a sequence of gauging and Higgsing for a $ℤ$2 symmetry. This prevents the gauge theory from developing a smooth quantum moduli space and affects the global structure of the gauge group, muting it from SO to O+.
