We study the BSFT actions by using an analytic continuation in momentum space. We compute various two- and three-point functions for some low-lying excitations including massive states on BPS/non-BPS D-branes. The off-shell two-point functions for the tachyon, the gauge field and the massive fields are found to reproduce the well-known string mass-shell conditions. We compare our action with the tachyon actions previously obtained by the derivative expansion (or the linear tachyon profiles…

It is proved that the on-shell physical amplitudes at the tree level are completely independent of the string length parameter ..cap alpha... the zero-slope limit of the covariant string action as well as of the BRS transformation is calculated completely off the mass shell.
Using string field theory, we argue that the tachyon potential on a D-brane in bosonic string theory in arbitrary background has a universal form, independent of the boundary conformal field theory
