Trinions for the 3d compactification of the 5d rank 1 ENf+1 SCFTs

Many interesting phenomena in quantum field theory such as dualities and symmetry enhancements can be understood using higher dimensional constructions. In this paper, we study compactifications of the rank 1 5d Seiberg E-Nf (+1) SCFTs to 3d on Riemann surfaces of genus g > 1. We rely on the recent progress in the study of compactifications of 6d SCFTs to 4d and torus compactifications of 5d SCFTs to conjecture 3d N = 2 theories corresponding to the reduction of said 5d SCFTs on three punctured spheres. These can then be used to build 3d N = 2 models corresponding to compactifications on more general surfaces. The conjectured theories are tested by comparing their properties against those expected from the compactification picture.
