TL;DR
This paper explores how a dyonic impurity, modeled as a D3-brane, catalyzes vacuum decay in a metastable state within the KKLT scenario, revealing that strong electromagnetic effects significantly reduce the vacuum's lifetime.
Contribution
It introduces a novel mechanism of vacuum decay catalysis via dyonic impurities in string theory compactifications, connecting D-brane physics with vacuum stability analysis.
Findings
Dyonic impurities enhance vacuum decay rate.
Strong electromagnetic fields on NS5-branes destabilize the vacuum.
Vacuum lifetime is drastically shortened by the impurity.
Abstract
We investigate catalysis induced by a dyonic impurity in the metastable vacuum studied by Kachru, Pearson and Verlinde, which can be relevant to vacuum decay in the KKLT scenario. The impurity is a D3-brane wrapping on in the Klebanov-Strassler geometry. The effect of the D3-brane can be encoded in the world-volume theory of an NS5-brane as an electromagnetic field on it. As the field strength becomes large, instability of the vacuum enhances. As a result, the lifetime of the metastable vacuum becomes drastically shorter.
