] | We examine the cosmological and astrophysical signatures of a "dark baryon," a neutral fermion that mixes with the neutron. As the mixing is through a higher-dimensional operator at the quark level, production of the dark baryon at high energies is enhanced so that its abundance in the early universe may be significant... |

group representations and chiralities of a single generation of fermions in the
Standard Model, augmented by a sterile neutrino. The model is a modification of
the world-line approach to chiral fermions.
