Abstract:
The richness of 5d N=1 theories with a UV
fixed point at infinite coupling is due to the
existence of local disorder operators known
as instanton operators. By considering the
Higgs branch of SU(2) gauge theories with
Nf≤7 flavours at finite and infinite coupling,
we write down the explicit chiral ring
relations between instanton operators, the
glueball superfield and mesons. Exciting
phenomena appear at infinite coupling: the
glueball superfield is no longer nilpotent
and the classical chiral ring relations are
quantum corrected by instanton operators
bilinears. We also find expressions for the
dressing of instanton operators of arbitrary
charge. The same analysis is performed for
USp(2k) with an antisymmetric
hypermultiplet and pure SU(N) gauge
theories.
