Abstract
We present a series of new gauge invariant quantities in Witten's open string field theory. They are defined for a given set of open string states which satisfy the physical state condition around a classical solution. For known classical solutions, we show that these gauge invariant quantities compute on shell tree-level scattering amplitudes around the correspondent D-brane configuration.
