We use quantum field theory methods to study the network model for the spin quantum Hall transition. When the couplings are fine tuned in a certain way, the spin and charge degrees of freedom, corresponding to the supercurrent algebras su(2)0 and osp(2|2)−2 respectively, decouple in the renormalization group flow. The infrared fixed point of this simpler theory is the coset osp(4|4)1/su(2)0 whi...
