$QCD_3$ Dualities and the F-Theorem

Understand

There has recently been a surge of new ideas and results for 2+1 dimensional gauge theories.

• We consider a recently proposed duality for 2+1 dimensional QCD, which predicts a symmetry-breaking phase.
• Using the F-theorem, we find bounds on the range of parameters for which the symmetry-breaking phase (and the corresponding duality) can occur.
• We find exact bounds for an $ SU(2) $ gauge theory, and approximate bounds for an $SU(N) $ gauge theory with $ N>2 $.
