Abstract
We find a 16-supersymmetric mass-deformed Bagger-Lambert theory with $SO(4)\ifmmode\times\else\texttimes\fi{}SO(4)$ global $R$ symmetry. The $R$ charge plays the role of the noncentral term in the superalgebra. This theory has one symmetric vacuum and two inequivalent broken sectors of vacua. Each sector of the broken symmetry has $SO(4)$ geometry. We find the $1/2$ BPS domain walls connecting the symmetric phase and any broken phase, and $1/4$ BPS supertubelike objects, which may appear as anyonic $q$-balls in the symmetric phase or vortices in the broken phase. We also discuss mass deformations, which reduce the number of supersymmetries.
