The 6d (2,0)-superconformal QFT admits a soliton solution which is a string charged under the self-dual B-field. Externally this is the boundary of the M2-brane ending on the M5-brane. As such this is “the string in M-theory” and hence is also called the M-string (e.g.Hohenegger-Iqbal 13).
The elliptic genus of the self-dual string at the boundary of the M2-brane on the M5-brane has been suggested to be directly analogous to the Todd genus of the boundary of the open superstring ending on D-branes and hence has been suggested to be the M5-brane charge in (Sati 10). Discussion of the computation of this elliptic genus includes (Hohenegger-Iqbal 13).

As a black brane the self-dual string in 6d was maybe first seen in
The appearance of self-dual string in six dimensions with an ADE classification was first observed in
As a Green-Schwarz sigma-model the brane scan-cocycle for the superstring in 6d is given in
