We show analytically that, under certain assumptions, the periodic Anderson model and the Hubbard model become equivalent within the dynamical mean field theory for quasiparticle weight Z to zero. A scaling relation is derived which is validated numerically using the numerical renormalization group at zero temperature and quantum Monte Carlo simulations at finite temperatures. Our result show that the f-electrons of the half-filled periodic Anderson model with nearest neighbor hybridization get localizaed at a finite critical interaction strength U_c, also at zero temperature. This transition is equivalent to the Mott-transition in the Hubbard model.
