Abstract
We identify spacetime symmetry charges of string theory from an infinite number of zero‐norm states (ZNS) with arbitrary high spin in the old covariant first quantized string spectrum. We give various evidences to support this identification. These include massive sigma‐model calculation, Witten string field theory calculation, 2D string theory calculation and, most importantly, three methods of high‐energy stringy scattering amplitude calculation. The last calculations explicitly prove Gross’s conjectures in 1988 on high energy symmetry of string theory.
