From N M2's to N D2's

Understand

In this short note, we reduce the N=6, U(N)xU(N) Chern-Simons gauge theories to N=8, U(N) Yang-Mills gauge theories.

• This process corresponds to recovering the world-volume theory of N D2-branes from that of N M2-branes in an intermediate energy range.
• The supersymmetries are enhanced because in this limit the branes localize far away from the orbifold singularity.
• Our main scheme is exactly in accordance with Mukhi and Papageorgakis's earlier work, although the Higgs mechanism becomes trickier in the present case.
