摘要：

In a large class of popular gauge models, electric charge quantization among the observed quarks and leptons has been shown to follow from anomaly constraints and the requirement of neutrinos being Majorana particles. Such theories allow new particles with arbitrary charges whose presence can lead to a variety of physical effects. In this paper, we show that observations from SN1987A rule out charges Qε{lunate} and masses mε{lunate} of these mini-charged particles in the range 10-9≤Q≤10-7 for mε{lunate}≤10MeV. © 1990.
