YangMills action from open superstring field theory
Abstract
We calculate the effective action for nonabelian gauge bosons up to quartic order using WZWlike open superstring field theory. After including level zero and level one contributions, we obtain with 75% accuracy the YangMills quartic term. We then prove that the complete effective action reproduces the exact YangMills quartic term by analytically performing a summation over the intermediate massive states.
