We consider the one band Hubbard model in the Slave Bosom formulation first introduced by Kotliar a.ud Ruckenstein. Applying a modified Mean Field Approxima.tion (MFA), I 1 11 w lit I a ows for broken symmetry st,ates, we numerically determine the values of the involved Bose fields at the saddle poi
