Query: Orbital Magnetism in the Cuprates   The pseudogap phase of the cuprate superconductors is argued to be
characterized by a hidden broken symmetry of d-wave character in the
particle-hole channel that leads to staggered orbital magnetism. This proposal
has many striking phenomenological consequences, but the most direct signature
of this order should be visible in the neutron scattering experiments. The
theoretical underpinning of these experiments is discussed.
