# S-Brane Actions (超弦理論の展望)

@inproceedings{Hashimoto2002SBraneA, title={S-Brane Actions (超弦理論の展望)}, author={Koji Hashimoto and Pei-Ming Ho and John E. Wang}, year={2002} }

We derive eﬀective actions for Spacelike branes (S-branes) and ﬁnd a solution describing the formation of fundamental strings in the rolling tachyon background. The S-brane action is a Dirac-Born-Infeld action for Euclidean worldvolumes deﬁned in the context of time-dependent tachyon condensation of non-BPS branes. It includes gauge ﬁelds and in particular a scalar ﬁeld associated with translation along the time direction. We show that the BIon spike solutions constructed in this system…
