General low energy dynamics of supersymmetric monopoles

We derive general low energy dynamics of monopoles and dyons in $N=2\mathrm{}$ and $N=4\mathrm{}$ supersymmetric Yang-Mills theories by utilizing a collective coordinate expansion. The resulting new kind of supersymmetric quantum mechanics incorporates the effects of multiple Higgs fields, both in the $N=2\mathrm{}$ vector multiplet and hypermultiplets, having non-vanishing expectation values.
