We show that the spontaneous breakdown of U(1) symmetry in a Higgs model canbe described in discretized light cone formulation even by neglecting zeromode. We obtain correctly the energy of a ground state with the symmetrybreakdown. We also show explicitly the presence of a Goldstone mode and itsabsence when the U(1) symmetry is gauged. In spite of obtaining the favorableresults, we lose a merit in the formulation without zero modes that a naiveFock vacuum is the true ground state.Comment: 7 page
