Abstract
When ghost coordinates are used in combination with the ∂Xμ and ψμ degrees of freedom, an infinite set of operators of conformal dimension one can be constructed for the open superstring. These conservation laws aid in computing the string scattering amplitudes for bosons and fermions. Using them and an additional trick, N-point correlation functions can be reduced to (N − 1)-point ones, so that any superstring tree-amplitude can be calculated in a manifestly Lorentz covariant form if the two-point correlation functions are known. The method is applicable to both closed and open strings and can be adapted to heterotic strings. Sample calculations are presented.
