对SU(2)hedgehog skyrmion解析解Hyb(4/4)参数的改进

An Improvement for the Parameters of an Analytical Solution Hyb(4/4) for the SU(2) Hedgehog Skyrmion

对SU(2)hedgehog skyrmion解析解Hyb(4/4)的参数和πNN耦合的计算方法进行了改进.改进后的解析解MHyb(4/4)与数值解更符合,误差也进一步减小,进而得知MHyb(4/4)为SU(2)Hedgehog skyrme模型更精确的解析解。

The parameters of an analytical solution Hyb（4/4） for the SU（2） hedgehog skyrmion and the calculaton method of the π NN-coupling improved.The result shows a better agreement between themodified Hyb（4/4）（MHyb（4/4）） and numerical solution and has smaller error,lonseguently,it makes further understanding toward MHyb（4/4） is a more accurate analytical solution for the SU（2） hedgehog syrmion.
