| Abstract: | Operator matrix elements are studied in a translation invariant version of the bag model in two-dimensional space time. In particular we calculate the matrix elements of quark fields Q(x), currents Jμ(x), and bilocal currents Q(x)γμλaQ(0) whose Taylor expansion yields the twist two operators of leptoproduction. The structure functions of this model are related to those of a naive cavity approximation by a particularly simple transformation. |
