论文摘要
我们使用BARYONS的大型$ N_C $作为手性孤子的图片来得出Baryons中四极能，弹性压力和剪切力分布之间的关系数量。所获得的大$ N_C $关系独立于特定的动态，并且应在Baryon是手性Soliton的任何图片中保持。 唯一图片的显着定性预测之一是，用于巴里昂的任何张量极化的切向力的无效。派生的关系提供了一种强大的工具，可以使用晶状体QCD来检查重手感孤子的假设。
We derive number of relations between quadrupole energy, elastic pressure, and shear force distributions in baryons using the large $N_c$ picture of baryons as chiral solitons. The obtained large $N_c$ relations are independent of particular dynamics and should hold in any picture in which the baryon is the chiral soliton. One of remarkable qualitative predictions of the soliton picture is the nullification of the tangential forces acting on the radial area element for any tensor polarisation of the baryon. The derived relations provide a powerful tool to check the hypothesis that the baryons are chiral solitons, say using lattice QCD.
