非阿贝尔快子扭结

Non Abelian Tachyon Kinks

Vincenzo Calò, Gianni Tallarita, Steven Thomas

摘要:

从两个重合的非BPS D9膜的作用出发,研究了U(2)矩阵快子场的扭结组态。我们认为这两个Str和Tr处方的非BPS行动的痕迹过规指数。非阿贝尔快子凝聚的理论与Tr处方,以及由此产生的波动的扭结轮廓,所示,引起的理论,两个符合BPS D8膜。这是一个自然的非阿贝尔推广森的机制,快子凝聚在一个单一的非BPS DP膜产生一个单一的BPS膜codimesion 1。相比之下,从Str规范迹线规定的一致非BPS D9膜作用量开始,森机制的这种概括似乎有问题。

英文摘要:

Starting from the action of two coincident non-BPS D9-branes, we investigate kink configurations of the U(2) matrix tachyon field. We consider both Str and Tr prescriptions for the trace over gauge indices of the non-BPS action. Non-abelian tachyon condensation in the theory with Tr prescription, and the resulting fluctuations about the kink profile, are shown to give rise to a theory of two coincident BPS D8-branes. This is a natural non-abelian generalization of Sen's mechanism of tachyon condensation on a single non-BPS Dp-brane yielding a single BPS brane of codimesion one. By contrast, starting with the Str gauge trace prescription of the coincident non-BPS D9-brane action, such a generalization of Sen's mechanism appears problematic.
