Abstract: (Elsevier)
We study numerically the classical behaviour of the Skyrme model coupled to an SU(2) L gauge field. We find that if the parameters of the model are chosen in such a way that the skyrmion mass is smaller than a critical value M crit , the Skyrmion is classical stable. For other values of the parameters there are no soliton solutions to the classical field equations, i.e. skyrmions are classical unstable. We calculate the critical values of the parameters and the critical mass of the skyrmion. We find that the transition between these two classical regimes is a first-order one. We comment on the implications of our results lto techicolor.- Skyrme model
