The temperature and doping dependence of the 2D Hubbard model is studied in the intermediate coupling regime U 4: Strong 2D critical spin fluctuations dominating near half-filling are completely destroyed upon about 14% doping concentration, below which the imaginary part of the self-energy vanishes
