Light Cone Gauge

We present an analysis of possible infinities that may be present in uncompactified multi-loop heterotic and type II superstring amplitudes constructed, without use of the short-string limit, in the light-cone gauge, and with use of a closed [10]-SUSY field theory algebra. Various types of degenerations of the integrand are discussed on the string world-sheet. No infinities are found, modulo (for type II) a particular identity for Green’s functions.

Full Algebra

Functional methods are used to give a complete closure of the second-quantized field theory nonlinear realization of the ten-dimensional super-Poincaré algebra for the heterotic superstring in the Green-Schwarz formalism. New terms in the fundamental generators JI−, J+− are constructed at quartic order in the fields so as to close the Poincare algebra; a quartic term in the Hamiltonian is also derived. No higher order terms are needed for any generators of the full algebra.
