Abstract
We provide numerical evidence for composite fermion pairing in quantum Hall bilayer systems at filling nu=1/2+1/2 for intermediate spacing between the layers. We identify the phase as p_x+i p_y pairing, and construct high accuracy trial wave functions to describe the ground state on the sphere. For large distances between the layers, and for finite systems, a competing ‘‘Hund’s rule’’ state, or composite fermion liquid, prevails for certain system sizes.
