New dark matter candidates motivated from superstring derived unification

PDF Version Also Available for Download.

Description

Perturbative gauge coupling unification in realistic superstring models suggest the existence of additional heavy down-type quarks, beyond the minimal supersymmetric standard model. The mass scale of the heavy down-type quarks is constrained by requiring agreement between the measured low energy gauge parameters and the string-scale gauge coupling unification. These additional quarks arise and may be stable due to the gauge symmetry breaking by ``Wilson lines`` in the superstring models. We argue that there is a window in the parameter space within which this down-type quark is a good candidate for the dark matter. 18 refs.
