String junctions suspended between giants

We construct $(p,q)$ string junction solutions suspended between both sphere and AdS giant gravitons in $AdS_5\times S^5$. Our results extend easily to more general half BPS geometries of LLM type. These carry angular momentum the directions worldvolume gravitons. argue that these are charged under a central extension supersymmetry algebra similar one has appeared works Beisert for ${\cal N}=4 $ spin chain. also they with respect this extension. show apart from some kinematical details, junctions end up solving same minimization problem appears Coulomb branch SYM. Their mass shape is independent $Q$ carries.
