Possibility of dynamical symmetry breaking (DSB) in scalarless SU(2) × U(1) is studied in weak coupling limit using an effective potential approach. In the linearized approximation we find that the model with a quark doublet can have DSB whereas the model with a lepton doublet cannot. When nonlinear effects, including those due to the non-abelian triple and quartic vector couplings, are included DSB is not realized.
