Recently a tachyon DBI action is proposed for describing the non-coincident D*_p*-brane-anti-D*_p*-brane system. For branes separation larger than *\sqrt{2\pi^2\alpha'}*, the tachyon potential has both false and true vacuums. We shall show that due to the non-standard form of the kinetic term in the effective action, the "overshoot" argument of Coleman... Show more
