反膜附近通量的观测

Observations on fluxes near anti-branes

Diego Cohen-Maldonado, Juan Diaz, Thomas Van Riet, Bert Vercnocke

摘要:

我们重新审视必要条件粘合当地(反)D3喉通量喉相反的电荷。这些一致性条件通常揭示了三种形式通量的奇异性,其意义正在争论之中。在本文中,我们证明了,在动机良好的假设下,非物理奇点可以潜在地避免时,反膜极化成球面NS5膜具有特定的半径。如果一个一致的解决方案,然后确实可以找到,我们的分析似乎表明,一个相当大的修正相比,探测结果的极化球的半径。我们进一步评论在有限温度下的胶合条件,并指出,一个特定的假设,最近的不去定理可以打破,如果反膜确实极化成球形NS 5膜在零温度。

英文摘要:

We revisit necessary conditions for gluing local (anti-)D3 throats into flux throats with opposite charge. These consistency conditions typically reveal singularities in the three-form fluxes whose meaning is being debated. In this note we prove, under well-motivated assumptions, that unphysical singularities can potentially be avoided when the anti-branes polarise into spherical NS5 branes with a specific radius. If a consistent solution can then indeed be found, our analysis seems to suggests a rather large correction to the radius of the polarization sphere compared to the probe result. We furthermore comment on the gluing conditions at finite temperature and point out that one specific assumption of a recent no-go theorem can be broken if anti-branes are indeed to polarise into spherical NS5 branes at zero temperature.
