NS5-brane

Urs Schreiber
In the context of string theory the NS5-brane is a certain extended physical objects – a brane – that appears in/is predicted by the theory. There are different incarnations of this object: For instance the effective background QFT of the type II string – type II supergravity – admits solutions to its generalized Einstein equations which describe higher dimensional analogs of charged black holes in ordinary gravity. Among them is a 5+1-dimensional “black brane” which is magnetically charged...
