Field theory of spinning strings

We present the field theory of spinning strings, which is a natural generalization of the field theory of Dirac particles. Because we place spinors along a string defined at each space-time point, the theory is at once multilocal and reproduces an infinite-component field theory. We introduce interactions by allowing the string to execute well-defined topological transformations and show that we reproduce the usual dual models of Neveu, Schwarz, and Ramond. We give the full Lagrangian which yields $S$ matrices which are dual, factorizable, Lorentz-invariant, crossing-symmetric, and probably renormalizable.
