The superoperator formalism of the Neveu-Schwarz-Ramond model

The Neveu-Schwarz-Ramond model is rewritten in terms of a new operator formalism where the old ones are combined into superoperators, i.e. an extra set of variables, anticommuting Grassman variables, is used besides the usual Koba-Nielsen variables to describe external legs in dual amplitudes. It is shown that many formulae become more compact and transparent and an operator formalism closer to a spinning string picture is found. The fermion emission vertex is shown to appear in a more natural way in a formalism like this. (Auth.)
