| contents | We report a brief overview ofa number of results on a type of pairing state symmetry in cuprates HTSC from a current literature. The results of recent high-precision measurements of near-nodal d-type gap functions by a modern laser-based ARPES method or by a c-axis twisted Josephson junction for hole-doped Bi-2212 system are presented. Recent experimental evidence in favor of d-type pairing symmetry, with a special nonmonotonic functional form, for electron-doped cuprate NdCeCuO is discussed. A new essential results on the identification of dx^2-y^2 symmetry of superconducting order parameter for parent high-Tc cuprate structure, electron-doped infinite layer SrLaCuO system, by the phase sensitive tests is described. A complex of the data presented indicates a vital role of d-wave pairing symmetry, in the special dx^2-y^2 form for high-temperature conductivity in cuprate systems. |
