Superstrings and dark matter
R. Dick, N. Eschrich, M. Gaul
We point out that the spectrum and interactions of light states of the heterotic string indicate a string scale close to the GUT scale, and a mass generating scale for the gravitat…

The string scale and the Planck scale
Rainer Dick
A particle spectrum below the string scale in accordance with predictions from heterotic string theory yields a Planck mass which exceeds the string scale b…
