Description |
This talk focuses on vacuum moduli spaces of 6d N=(1,0) field theories that have a superconformal fixed point at infinite coupling. Such theories admit an effective description in terms of a quiver diagram, which can be realised using Type IIA string theory or F-theory at finite coupling. We show that several pieces of information about the hypermultiplet moduli space, also known as the Higgs branch, of the superconformal field theory (SCFT) at infinite coupling are drastically different from those obtained naively from the quiver at finite coupling. However, using a torus compactification to lower dimensional field theories as a tool, we show how one can extract the information about the Higgs branch of the SCFT at infinite coupling from the finite coupling description. This provides several insights into the physics at infinite coupling of six dimensional field theories. |
