A generalized Schwinger boson representation is proposed to describe the two-dimensional SU(4) symmetric spin-orbital quantum antiferromagnet. A uniform mean field solution gives rise to an antiferromagnetic long range ordered state with a small staggered magnetization ms=0.07566, and the recent quantum Monte Carlo simulations on rather large lattice sizes have provided strong evidence to support these mean field results.
