## Existence and stability of gauged non-topological solitons

In this paper classical non-topological soliton configurations are considered in a theory with a local U(1) symmetry. Their existence, stability against dispersion into free particles are studied numerically. As in the case of Friedberg, Lee, and Sirlin with a global U(1) symmetry, also in this case there are two critical charges; Q{sub c} for the existence and Q{sub s} for the stability of the non-topological soliton configurations. Our numerical results show that the magnitudes of both Q{sub c} and Q{sub s} increase as the magnitude of the gauge coupling constant e is increased with the other parameters kept at fixedmore »
