Abstract
We study quantum corrections at the one-loop level in open superstring tach yon condensation using the boundary string field theory (BSFT) method. We f ind that the tachyon field action has the same form as at the disc level, b ut with a renormalized effective coupling lambda' = g(s)(ren) e (-T2/4) (g( s)(ren) is the renormalized dimensionless closed string coupling, e(-T2/4) is the tachyonic field expectation value) and with an effective string tens ion. This result is in agreement with that based on general analysis of loo p effects.
