Complete supersymmetric quantum mechanics of magnetic monopoles in N=4 super Yang-Mills theory - art. no. 025009

We find the most general low energy dynamics of 1/2 BPS monopoles in the N = 4 supersymmetric Yang-Mills (SYM) theories when all six adjoint Higgs exp ectation values an turned on. When only one Higgs value is turned on, the L agrangian is purely kinetic. When all the remaining five are turned on a li ttle bit, however, this moduli space dynamics is augmented by five independ ent potential terms, each in the form of half the squared norm of a Killing vector field on the moduli space. A generic stationary configuration of th e monopoles can be interpreted as stable non-BPS dyons, previously found as nonplanar string webs connecting D3-branes. The supersymmetric extension i s also found explicitly, and gives the complete quantum mechanics of monopo les in N = 4 SYM theory.
