相交膜真空之间的非微扰跃迁

Non-perturbative transitions among intersecting-brane vacua

Carlo Angelantonj, Cezar Condeescu, Emilian Dudas, Gianfranco Pradisi

摘要:

我们调查的蜕变D-膜到阿贝尔磁背景上的世界体积的高维膜,在全球模型的框架内,紧凑的内部尺寸。交叉膜图中的T-对偶到膜复合现象,与非紧空间中的逆小瞬子跃迁有一些相似之处,尽管在这种情况下阿贝尔磁背景是内部流形的紧性的结果,而不是归因于零尺寸非阿贝尔瞬子增长到最大尺寸。我们提供了各种超对称orientifolds和非超对称快子无真空与膜超对称性破缺,无论是从膜重组和从场论希格斯机制的观点过渡的细节。

英文摘要:

We investigate the transmutation of D-branes into Abelian magnetic backgrounds on the world-volume of higher-dimensional branes, within the framework of global models with compact internal dimensions. The phenomenon, T-dual to brane recombination in the intersecting-brane picture, shares some similarities to inverse small-instanton transitions in non-compact spaces, though in this case the Abelian magnetic background is a consequence of the compactness of the internal manifold, and is not ascribed to a zero-size non-Abelian instanton growing to maximal size. We provide details of the transition in various supersymmetric orientifolds and non-supersymmetric tachyon-free vacua with Brane Supersymmetry Breaking, both from brane recombination and from a field theory Higgs mechanism viewpoints.
