Résumé :

The symmetries of the order parameter (OP) responsible for pairing and the OP responsible for phase coherence in hole-doped cuprates are discussed. We analyze angle-resolved tunneling, angle-resolved photoemission (ARPES), Raman scattering and torque measurements performed on hole-doped cuprates. We conclude that, most likely, the OP responsible for phase coherence has the dx(2)-y(2) symmetry whereas the OP responsible for pairing has an anisotropic s-wave symmetry.
