Four-dimensional supersymmetric SU(N) Yang-Mills theory on a sphere has
highly charged baryon-like states built from anti-symmetric combinations of the
adjoint scalars. We show that these states, which are equivalently described as
holes in a free fermi sea of a reduced matrix model, are D-branes. Their
excitations are stringlike and effectively realize Dirichlet and Neumann
boundary conditions in various directions. The low energy brane dynamics should
realize an emergent gauge theory that is local on a new space. We show that the
Gauss' Law associated to this emergent gauge symmetry appears from
combinatorial identities relating the stringy excitations. Although these
excitations are not BPS, they can be near-BPS and we can hope to study them in
perturbation theory. Accordingly, we show that the Chan-Paton factors expected
for strings propagating on multiple branes arise dynamically, allowing the
emergent gauge symmetry to be non-Abelian.Comment: 55 pages, 9 figures,uses young.sty (included). v2: reference added.
