    "abstract": "We propose a new mean-field-type framework which can treat the strong\ncorrelation induced by the tensor force. To treat the tensor correlation we\nbreak the charge and parity symmetries of a single-particle state and restore\nthese symmetries of the total system by the projection method. We perform the\ncharge and parity projections before variation and obtain a Hartree-Fock-like\nequation, which is solved self-consistently. We apply the Hartree-Fock-like\nequation to the alpha particle and find that by breaking the parity and charge\nsymmetries, the correlation induced by the tensor force is obtained in the\nprojected mean-field framework. We emphasize that the projection before the\nvariation is important to pick up the tensor correlation in the present\nframework.",
