Large solitons flattened by small quantum corrections

Abstract

We propose a general form of the UV-completed Friedberg-Lee-Sirlin (FLS) model. As can be seen from the Newtonian mechanics interpretation, UV-completion allows thin-wall approximation for non-topological solitons. The 1-loop renormalized effective potential for the UV-completed FLS model is constructed under the assumption of mass hierarchy. By special choice of parameters, we studied how the Coleman-Weinberg mechanism induces a new mass scale ω− in the classical FLS model. It can be expounded in terms of a stable condensate. As a consequence, the asymptotic behavior of a non-topological soliton's energy at large charge is changed from ∼Q3/4 to the linear law.
