关于弦论IIB型1/4 BPS((F,D1),(NS5,D5))束缚态

On 1/4 BPS ((F, D1), (NS5, D5)) bound states of type IIB string theory

Qiang Jia, J. X. Lu, Shibaji Roy

摘要:

我们构造了两个新的IIB型弦论SL(2,Z)不变真空,它们是$(m,n)$ 5-膜的$(p,q)$弦的束缚态,记作((F,D1),(NS 5,D5)),并保持了1/4的时空超对称性.在第一种情况下,弦存在于5-膜世界体积中,而在第二种情况下,弦垂直于5-膜世界体积。在第一种情况下,人们会天真地认为弦和5-膜之间存在吸引相互作用,因为F和D5之间以及D1和NS 5之间存在吸引力。我们发现,只有当真空模量满足一定的条件时,才存在1/4 BPS束缚态,该条件与膜间无力条件一致。第二种情况则没有这种并发症。张力公式和其他各种后裔状态,可以通过应用T-对偶这两个束缚态进行了讨论。

英文摘要:

We construct two new SL(2,Z) invariant vacua of type IIB string theory which are bound states of $(p,q)$ strings with $(m,n)$ 5-branes, written as ((F, D1), (NS5, D5)) and preserve 1/4 of the full space-time supersymmetries. For the first case, the strings live inside the 5-brane world-volume and in the second case the strings are perpendicular to the 5-brane world-volume. In the first case, naively one would expect an attractive interaction between the strings and the 5-branes due to attractive force between F and D5 and also between D1 and NS5. We find that 1/4 BPS bound state exists only when the vacuum moduli satisfy certain condition which is found to be consistent with the no-force condition between the branes. No such complication arises for the second case. The tension formulae and the various other descendant states which can be obtained by the application of T-duality for both these bound states are discussed.
