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