Abstract: (Elsevier)
We calculate the n -point correlation functions of spin fields on an arbitrary genus Riemann surface. We also calculate the corresponding correlators for the spin fields associated with the local supersymmetry ghosts using a specific ansatz for screening the background ghost charge. Using these results we show by explicit calculation that to all orders in the string perturbation theory all n -point amplitudes involving massless fields in the superstring and the heterotic string theory vanish identically for 0 ⩽ n ⩽ 3.- MODEL: STRING
