标题： An attractive nucleon-nucleon spin-orbit force from skyrmions with dilatons

摘要： 在核子-核子力的skyrmion方法中，获得一个标量吸引自旋-轨道势遇到了困难，这与寻找标量中心势中的吸引力问题并行存在。 我们在此研究使用拉格朗日量中具有四阶和六阶导数稳定项的skyrmion，以及关键添加的dilaton的自旋-轨道力。 在这些特性存在的情况下，自旋-轨道力是吸引的，中心势也是如此。 在没有dilaton的情况下，也可以在自旋-轨道势中找到吸引力，但只能以六阶导数项被大大强调为代价，并且中心势中持续缺乏吸引力。 显示英文摘要

摘要： Within the skyrmion approach for the nucleon-nucleon force, difficulties have been experienced in obtaining an isoscalar attractive spin-orbit potential, in parallel to the problems of finding attraction in the isoscalar central potential. We here study the spin-orbit force using a skyrmion with four- and six-derivative stabilizing terms in the lagrangian as well as with the crucial addition of a dilaton. With these features present the spin-orbit force proves to be attractive as does the central potential. In the absence of the dilaton, attraction can also be found for the spin-orbit potential but only at the expense of a greatly over-emphasized term with six derivatives and a continuing absence of attraction in the central potential.
