By studying the deformations of conformal field theories in the operator formalism, it is proved that to every primary field of dimension one there corresponds a gauge transformation. An infinite class of such gauge transformations is constructed, most of which relate string states of differing mass. It is argued that these symmetries are spontaneously broken by the space-time metric, but that this breaking becomes unimportant for high-energy scattering, thus shedding light on the results of Gross and Mende.Read More
