A theory for the high temperature superconductors is proposed. Holes arespin-1/2, charge e, quasiparticles strongly dressed by spin fluctuations. Basedon their dispersion, it is claimed that the experimentally observed van Hovesingularities of the cuprates are likely originated by antiferromagnetic (AF)correlations. From the two carriers problem in the 2D t-J model, an effectiveHamiltonian for holes is defined with %no free parameters. This effective modelhas superconductivity in the ${\rm d_{x^2-y^2}}$ channel, a criticaltemperature ${\rm T_c \sim 100K}$ at the optimal hole density, ${\rm x=0.15}$,and a quasiparticle lifetime linearly dependent with energy. Other experimentalresults are also $quantitatively$ reproduced by the theory.Comment: 12 pages, 4 figures (on request), RevTeX (version 3.0), preprint  NHMF
