Reasonable Behavior

The Coulomb problem for vector bosons W± incorporates a known difficulty; the boson falls on the center. In QED the fermion vacuum polarization produces a barrier at small distances which solves the problem. In a renormalizable SU(2) theory containing vector triplet (W+, W-, γ) and a heavy fermion doublet F with mass M the W- falls on F+ to distances r ~ 1/M, where M can be made arbitrary large. The collapse may be prevented if the theory contains additional light fermions or scalars, which switch the ultraviolet behavior of the theory from anti-screening to screening. Similar situation can take place in the Standard Model. Thus, the renormalizability of a theory may be not sufficient to guarantee a reasonable behavior at small distances for nonperturbative problems, such as a bound state problem.
