标量形状因子与核相互作用

Scalar form factors and nuclear interactions

M. R. Robilotta, G. R. S. Zarnauskas

摘要:

双π介子交换$NN$势中的标量-等熵项异常大,不符合手征微扰理论所预言的效应层次。我们认为,这种异常与非微扰效应,这也是目前在$πN$标量形状因子。

英文摘要:

The scalar-isoscalar term in the two-pion exchange $NN$ potential is abnormally large and does not respect the hierarchy of effects predicted by chiral perturbation theory. We argue that this anomaly is associated with non-perturbative effects, which are also present in the $πN$ scalar form factor.
