摘要：

We study the sphaleron solutions in the singlet majoron model and evaluate the sphaleron energy E(MM) in an accurate approximation. We show that E(MM) is restricted to vary within the range of variation of the standard model sphaleron energy E(SM) (lambda). As the VEV of the singlet scalar responsible for the breaking of the global U (1) is increased, E(MM) --> E(SM) (lambda(eff)) with lambda(eff) = lambda(1 - gamma-2/4-beta-lambda), where beta and gamma are couplings in the Higgs-singlet potential.
