摘要：

It is shown that within an effective model of QCD, the Lee-Wick model, bodies with quark content of mass of the order of 10(-2) to one solar mass can be formed at a temperature T similar to 1 MeV much lower than the quark-hadron phase transition temperature. This ensures their stability until the present epoch, and we suggest that they can be identified with the dark objects observed recently by gravitational microlensing.
