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 aspects of the hypermultiplet moduli space, also known as
the Higgs branch, of the superconformal field theory (SCFT) at infinite
coupling may drastically be different from those obtained naively from the
quiver at finite coupling. 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.
