Higher Order Term and Dynamical Behavior of Skyrmion.
Nguyen Vien Tho and To Ba Ha

The equation of motion for the time-dependent hedgehog for a generalized Skyrme model including sixth-order stabilizing term is derived and integrated numerically. The time evolution of soliton is obtained for two cases: with and without an initial perturbation. For the considered model, besides thermalization which has been found in the Skyrme model, we have observed the self-excitation of soliton because of the fast development of fluctuation.
Key words: Skyrme model, soliton,self-excitation.
