Using variational cluster perturbation theory we study the competition between d-wave superconductivity (dSC) and antiferromagnetism (AF) in the t\mathrm\text\ensuremath-t^\ensuremath'\mathrm\text\ensuremath-t^\ensuremath'\ensuremath'\mathrm\text\ensuremath-U Hubbard model. Large scale computer calculations reproduce the overall ground-state phase diagram of the high-temperature superconductors as well as the one-particle excitation spectra for both hole and electron doping. We identify clear signatures of the Mott gap as well as of AF and of dSC that should be observable in photoemission experiments.
