A Model of Field Theory with Nonvanishing Renormalized Charge
Abstract
Two fermion fields are considered in a space of one dimension (and in time), with interaction of each field with itself and of the two with each other. The first term in the expansion of the vertex part in an asymptotic series of well known form is obtained. It is shown that within certain limits the renormalized charge can have an arbitrary (nonvanishing) value.
