SUSY monopole potentials in 2+1 dimensions [PDF]
Journal of High Energy Physics, 2017 Gauge theories in 2+1 dimensions can admit monopole operators in the potential. Starting with the theory without monopole potential, if the monopole potential is relevant there is an RG flow to the monopole-deformed theory. Here, focusing on U(N c ) SQCD
