Query: Covariant open bosonic string field theory on multiple D-branes in the
  proper-time gauge   We construct a covariant open bosonic string field theory on multiple
D-branes, which reduces to a non-Abelian group Yang-Mills gauge theory in the
zero-slope limit. Making use of the first quantized open bosonic string in the
proper time gauge, we convert the string amplitudes given by the Polyakov path
integrals on string world sheets into those of the second quantized theory. The
world sheet diagrams generated by the constructed open string field theory are
planar in contrast to those of the Witten's cubic string field theory. However,
the constructed string field theory is yet equivalent to the Witten's cubic
string field theory. Having obtained planar diagrams, we may adopt the
light-cone string field theory technique to calculate the multi-string
scattering amplitudes with an arbitrary number of external strings. We examine
in detail the three-string vertex diagram and the effective four-string vertex
diagrams generated perturbatively by the three-string vertex at tree level. In
the zero-slope limit, the string scattering amplitudes are identified precisely
as those of non-Abelian Yang-Mills gauge theory if the external states are
chosen to be massless vector particles.
