We calculate the spectrum of the charge zero sector in two-dimensional quantum electrodynamics (massive Schwinger model). The calculations are first done in the rest frame with the perturbative vacuum within \(q \bar{q}\) and \(q q \bar{q} \bar{q}\) subspaces. This leads to the infrared instability

The Schwinger model is quantum electrodynamics with massless fermions in two dimensions. It is known that the asymptotic states of the theory contain no states corresponding to free fermions ("quark trapping") and that local charge conservation is spontaneously broken ("Higgs phenomenon"). We invest
