Abstract
En 中文
We combine two partons on a random lattice as a vector state. In the ladder approximation, we find that such states have 1/p(2) propagators (after tuning the mass to vanish). We also construct some diagrams which are very similar to 3-string vertices in string field theory for the first oscillator mode. Attaching 3 such lattice states to these vertices, we get Yang-Mills and F-3 interactions up to 3-point as from bosonic string (field) theory. This gives another view of a gauge field as a bound state in a theory whose only fundamental fields are scalars. (C) 2008 Elsevier B.V. All rights reserved.
