Abstract
We propose a hierarchy of spin liquids with spin , which are generated via a Schwinger boson projection from (Abelian) chiral spin liquids with . We argue that the P and T invariant liquids we construct for integer spin support SU(2) level non-Abelian statistics. We conjecture that these spin liquids serve as paradigms for antiferromagnets which are disordered through mobile charge carriers.
