Self-dual Strings and 2D SYM

Understand

We study the system of M2-branes suspended between parallel M5-branes using ABJM model with a natural half-BPS boundary condition.

• For small separation between M5-branes, the worldvolume theory is shown to reduce to a 2D N=(4,4) super Yang-Mills theory with some similarity to q-deformed Yang-Mills theory.
• The gauge coupling is related to the position of the branes in an interesting manner.
• The theory is considerably different from the 2D theory proposed for multiple "M-strings".
