Universal Features of BPS Strings in Six-dimensional SCFTs

Understand

In theories with extended supersymmetry the protected observables of UV superconformal fixed points are found in a number of contexts to be encoded in the BPS solitons along an IR Coulomb-like phase.

• For six-dimensional SCFTs such a role is played by the BPS strings on the tensorial Coulomb branch.
• In this paper we develop a uniform description of the worldsheet theories of a BPS string for rank-one 6d SCFTs.
• These strings are the basic constituents of the BPS string spectrum of arbitrary rank six-dimensional models, which they generate by forming bound states.
