摘要：

A perturbation expansion to all orders in loops is developed for the E8 x E8 heterotic string. A light-cone gauge lagrangian is presented and applied within the functional-integral formalism of Mandelstam to compute scattering amplitudes. Unitarity is manifest and the final answer is Lorentz invariant. It is shown that the determinant arising from the functional integration associated with the compactified degrees is analytic. This along with its modular properties, gives a unique specification of it up to an overall moduli-independent factor.
