Abstract
A zero mode bosonization technique treatment of the Hamiltonian is applied to the calculation of the persisten current carried by a Luttinger liquid with a single impurity. Analytical expressions are obtained for the suppression of the current as function of the impurity strength and the electron-electron interaction. The expression in the weak limit is confirmed numerically.
