中子负中心荷密度:一种包含-排斥关系

The neutron negative central charge density: an inclusive-exclusive connection

Gerald A. Miller, John Arrington

摘要:

模型的广义部分子分布在零偏度的深度非弹性散射夸克分布的行为,在高x的评估,在小距离的横向电荷密度评估。我们得到了最近获得的中子的负中心荷密度的解释。d夸克在Bjorken x值较大的情况下主导中子结构函数,在这种情况下,撞击夸克的大动量对确定动量中心有重要影响,从而对确定横向位置平面中核子的“中心”有重要影响。

英文摘要:

Models of generalized parton distributions at zero skewness are used to relate the behavior of deep inelastic scattering quark distributions, evaluated at high x, to the transverse charge density evaluated at small distances. We obtain an interpretation of the recently obtained negative central charge density of the neutron. The d quarks dominate the neutron structure function for large values of Bjorken x, where the large momentum of the struck quark has a significant impact on determining the center of momentum, and thus the ``center'' of the nucleon in the transverse position plane.
