5-brane webs, symmetry enhancement, and duality in 5d supersymmetric gauge theory

A bstractWe present a number of investigations of 5d

Lifting 4d dualities to 5d

Discrete θ and the 5d superconformal index

= 1 supersymmetric gauge theories that make use of 5-brane web constructions and the 5d superconformal index. These include an observation of enhanced global symmetry in the 5d fixed point theory corresponding to SU(N) gauge theory with Chern-Simons level ±N , enhanced global symmetries in quiver theories, and dualities between quiver theories and non-quiver theories. Instanton contributions play a crucial role throughout.
