Abstract
States on the Coulomb branch of 
= 4
super-Yang-Mills theory are studied from the point of view of
gauged supergravity in five dimensions. These supersymmetric
solutions provide examples of consistent truncation from type-IIB
supergravity in ten dimensions. A mass gap for states created by
local operators and perfect screening for external quarks arise in
the supergravity approximation. We offer an interpretation of
these surprising features in terms of ensembles of brane
distributions.
