Abstract:
Massive states (with energies $\gtrsim10$ GeV) of a hadronic string (with a scale $\alpha'\approx1$ GeV$^{-2}$) can have a very small coupling to ordinary baryons in the Universe. The lifetime of such states is of the order of or even greater than the age of the Universe. These heavy states are assumed to be possible candidates for the role of weakly interacting heavy dark-matter particles.
Keywords:
hadronic string, dark matter, weakly interacting heavy particle.
