3d N=2 mirror symmetry, pq-webs and monopole superpotentials

Understand

D3 branes stretching between webs of (p,q) 5branes provide an interesting class of 3d N=2 theories.

• For generic pq-webs however the low energy field theory is not known.
• We use 3d mirror symmetry and Type IIB S-duality to construct Abelian gauge theories corresponding to D3 branes ending on both sides of a pq-web made of many coincident NS5's intersecting one D5.
• These theories contain chiral monopole operators in the superpotential and enjoy a non trivial pattern of global symmetry enhancements.
