横平面上的强子动量密度

Hadronic Momentum Densities in the Transverse Plane

Zainul Abidin, Carl E. Carlson

摘要:

我们研究的空间密度扩展对象的动量分量$p^+$,并找到相对论精确的连接到傅立叶变换的引力形状因子。我们应用这些结果得到半经验的核子内的动量密度分布,并根据AdS/QCD对应的理论结果为自旋为1的对象类似的分布。我们发现,在横向平面上的动量密度比电荷密度更紧凑。

英文摘要:

We examine the spatial density within extended objects of the momentum component $p^+$, and find relativistically exact connections to Fourier transforms of gravitational form factors. We apply these results to obtain semi-empirical momentum density distributions within nucleons, and similar distributions for spin-1 objects based on theoretical results from the AdS/QCD correspondence. We find that the momentum density in the transverse plane is more compact than the charge density.
